Hi Mark I've got 2007 sachs speedforce 50 2 stroke last summer I bought a new carb for my bike worked like a dream. Then I left it for 5 months without starting it n now my carburettor isn't sucking the fuel through I tested it myself by sucking the vacuum and it comes out perfect but when I turn it over with the carb it isn't sucking it through. Also when I put new carb on it got a new fuel tap and filter the jets aren't blocked either.

[@marksavage]

well half of what I was going to say you have done so that's good so far vacuum , cleaned carb , fuel pipes --check ok now not so good stuff check the reeds and make sure they are closed ,so you did the wet hand carb test and was it wet ? don't like to say but it could be your oil seals!! id try with easy start and fuel down the head , try and start then clean plug and try and again to see

[@thomaswitty4016]

I have checked my reeds and they are all good I think it might be the Crank seals because when my engine is running there is this black liquid dripping from underneath the engine. Have you got Facebook so I can talk to you on there so it is easier

[@piotrnowak2219]

maybe you remember what the standard setting is for the idle speed screw?, 3.5 turns from the end to the fuel-air mixture and how much is for idle, I have the same carburetor and speedfight too. I did not notice that turning this screw somehow changed the idle speed.

[@marksavage]

Morning bud , there is no real standard setting for the idea on a old moped , just in till it runs ,well stays running Air mix is important like in my tuning video then idea as it runs bud If your going all the way in then needle hight needs adjusting as in my carb videos

[@harrydrake6079]

Hello Mark, fellow sub ive watched your videos and they have helped me in the long run! I bought a speedfight 2 for £50 none running and another one for £220 running i used the running engine for my other bike. But the £50 one i got running using your videos and to be honest it was just simple as the kick start wasnt engaging, but cleaned it up and its now in a garage getting front break sorted in it way for a mot! Many thanks! Harry Ps would love a shout out 👌

[@marksavage]

That's great to hear my videos help and you have managed to get them running well done bud and thanks for watching mark

[@harrydrake6079]

mark savage its moted tomorrow hopefully! Break sorted just didnt start for mot :(

[@marksavage]

oh maybe a little easy start will help, check the carb again .

[@harrydrake6079]

They said they'll be cleaning, have you not got facebook or anything i can show you progress through watching your videos

[@harrydrake6079]

So good news and bad news Good news it passed with two advisorys mirrors and front tyre Bad news it does idle and rev up but doesnt feel like it wants to move? Could it be the clutch? Does have new belt

[@kjellringstrom6217]

Hi mark. I might be able to get my hands on a Dellorto PHVA 17,5 from a Piaggio Zip. How would my SF2 run on that one? I know what intake manifold i need for it, and I will put a proper filter on it, and not any of those silly shower sponges.

[@marksavage]

If the old carb is bad then replace You should be able to set it up , change the main needle and slide Have a video on that Tune and change the jet with the old one Can't hurt bud

[@Jeff-g1k]

Hi I know this video is old but you have a helped me alot haha in the time but I’m having a bit of trouble with my carb just put a new carb and reeds on mine sp2 50cc 2t it’s running and reving and idling pretty good but won’t budge over 5-10mph it’s had new rollers few month ago new clutch 7-8 month ago but I don’t understand what’s the issue if you can help be appreciate thanks u

Hi, your videos are very good. I have the problem that the air filter is full of gasoline What could it be?

[@marksavage]

Vacuum leaking Test like in my videos Or Float

[@Browne-dv8we]

Hello agin mark, just one question my carb keeps flooding with oil what would cause this pease even if I leave the bike 3 days when I go to the bike there’s a massive leak of 2 stroke oil on the floor checked everywhere around the pump ect no leaks took air filter off and it’s full of oil

[@stephencresswell4760]

Last time I saw dirt like that it was because the previous owner had been using an old metal Jerry can. It had been crushed and the enamel had flaked off the inside. Then the metal had rusted and all the fuel was full of rust.

[@phillipdavey3868]

How is the autochoke attached to the top of the carb,ie how do you remove it?should it just pull off or those 2 small screws keeping it attached.2007 speedfight 100,thanks

[@marksavage]

Two small screws on a half washer keep it on connect Once removed it just twists out

[@brir2108]

Hi Mark, could do with your help. speedfight 2 50cc. The carb is an original gurtner but the adjustment screw is weird (basically a blank screw) and can't be adjusted and the autochoke is stuck in and it massively over revs. My question is....... the gurtner carbs are impossible to get a hold of so the only option is an aftersales £25 carb from ebay. Do I just replace it or try to get gurtner carb working as I hear they are really good. Appreciate your thoughts

[@teddybeer069]

I bought a Peugeot Speedfight 2 air-cooled, it has stood still for 8 years, it has been serviced, I replaced the old petrol and oil and the spark plug carburetor is clean but smokes a lot. I cannot adjust the carburetor, is it better that I buy a new carburetor i did al the things you did and nothing work its starts fine but a lot of smoke and if you wil drive its worse ??

[@marksavage]

You can adjust the carbs as in my carb videos and there's a fee Use a hack saw to line the screw However if not started in 8 years There might be all sorts in the sum I'd change piston anyway You don't know why it was left for 8 years!! Or new carb Whats the spark like There's 100 videos bud they will help

[@linihughes5106]

Hi Mark I was hoping u could help me as I'm having trubble with my Speedfight 2 it's a standard 50cc no power pipe or fancy carb or filter. The problem is it's eating spark plugs iv replaced the the spark plugs 4 times this month and I don't get it as I don't us it apart from ride it around the garden about 3 times a day well that's if it starts. Hope u and your family are doing well.

Hey mark just about to upgrade to a 17.mm carb from this exact carb your reassembled in this video. My new 17.5mm TNT carb as a vacuum connection at the top, where my original carb on the speedfight hasn’t got one? How do I set this up lol

[@marksavage]

As long as fitments are the same and fuel pipes set air mix 3 half turns out to start Follow my tuning video I've got lots of carb videos bud that should help

[@dwr-cchs7724]

Hi Mark, I hope you had a very merry christmas but on my air to petrol mix (3 half turns out) isn't a flat head screwdriver it's a weird shape and i can't get a screwdriver in to adjust it, What Should I do?

[@stephentowse4453]

We have a 2 stroke cpi Oliver that's had almost everything done to get it to run well and it's speedo is showing 50mph now, but it's always needed only 1/4 turn out of the air screw or it hardly runs at all? Very odd?

[@marksavage]

that a good speed, as for the carb, its a standard setting and each carb are different running set up so as long as its running and running well all is good check the plug and see what colour it is after a good run as you are looking for a nice light brown colour

[@youssefdaking]

hey mark thanks again for this video , as you said 3 half turns for the fuel air mix , but what about the screw with a spring on it ?

[@marksavage]

that's your idle and adjust that to keep the revs up or bring them down as you adjust the idle I have another newer video on my channel tuning in a 125 carb but it will show you how and the basics like his video kzbin.info/www/bejne/bJPbi2adfpx2qdk or kzbin.info/www/bejne/mZulipaYpLeghKM well worth a watch as I do have over 400 videos

[@dzasmiinbmk8600]

That screw what you must turn three half turn on my speedfight 2 is flat there is not head to screw it just flat why is that

[@matthewmarshall2270]

Hayup mark pal, great vids seriously, iv just a question, as im rideing my 50cc 2t, sx sachs moped, when im going some speed at full revs im starting to get a slight bogging, or like the fuels not getting in, or maybe air, im not sure what the problem could be any suggestions. ONLY on full revs tho, could it be so simple as to cleaning the carb,? Or should i try spraying carb cleaner in carb. ? Or the mixture..? Im lost pal. I do no though, my mixture screw is only about 1 turn out, but seems to be idling ok.. thanks mark. Hope to hear from you soon..

[@marksavage]

Matthew Marshall a service can only help I’d take the carb off and clean it like in my carb videos New plug and clean or change the air filter See how that goes if still the same I’d go to 3 half turns then jetting bud as carb and curling. do change after many miles Thanks for watching bud please like and sub and see how that goes Mark

[@LukeRoeYT]

I have a speedfight 3 that turns over but won’t start it has a strong new battery and spark I have fuel when I pull the pipe off and I have a brand new carb and the Reed valve has recently been replaced the bike only sounds like it wants to start when easy start is sprayed into the carb...any ideas of what else piston maybe? Thankyou I’m advance

[@marksavage]

Does it back fire or pop if you try and start it with the throttle open If so I'd go with piston Otherwise do wet hand test then it maybe engine / oil seals bud Loads of videos on my channel that will help

[@duncangallagher8702]

HELLO mARK.i HAVE A NEW CARB WITH A COOPER PIPE FOR THE OIL PUMP TO CARB HOSE DOES THIS COME OUT & YOU PUSH THE SMALL CONNECTOR INTO THE CARB Cheers Duncan.

[@marksavage]

take you have bought a Chinese part carb, you may have to enlarge the pipe or add a bit of bigger pipe to it, on the air mix keep the air mix screw all the way in and not 3 half turns unless it runs bad hope that helps please like and sub mark

[@youssefdaking]

hey mark thanks for your speedfight videos i have just a little question will these 3 turns help with mileage or this another setting for better mileage ? thanks

[@marksavage]

this helps your moped run at its best once tuned so 3 half turns is standard and adjustment after in of out, once running starting better the moped should be faster and more mpg don't forget to service the moped

[@youssefdaking]

thanks mark , i appreciate it , but i have another question XD srry for bothering u , the thing is i cant find an air filter replacement for the speedfight , so should i rock those chinese air filters that u hate XD ? thanks

[@marksavage]

you can take out the sp3 and take the fluffy part off clean and wash the foam part, but do have a look through e bay or google moped parts

[@youssefdaking]

mark savage yeah but the foam is cut on the middle and has a hole XD , ebay wont send to my country tho , i really wanna go for those round filters

[@marksavage]

Youssef you know I don’t like them but as long as it’s dry where you are then go for it It will be noisier and need a bit more tuning but should be fine

[@danielstewart7841]

Hi mark I bought a speed fight for getting to work it’s a 2006 and when I went to pick it up guy gave me a bottle and told me I had to mix it in tank. I also noticed that oil tank was removed and the oil pipe to carb was blocked off. What do I need to do to get the oil pump working again.

[@marksavage]

I have over 80 videos to hear they have 2 sort of 2t oil pumps, electric and manual so you need to check which one you have first change pump and refit oil tank , most of the time they stop using them because they have broken or they what more 2t oil in pre mix works but is not the best way

[@raul67slo]

Hi Mark - I have another question. I just cleaned the carb and when I got to reassembly and I put the oil hose (pin) back in I mounted it a bit too loosely and when i realized this I expected to see some oil dripping out but there was none - I only had the engine running on idle but I would still expect a drop or two leaking out - or is it in such small amounts that it didn't come out yet? I was wondering if there is a way to check if the oil actually gets into the carb?

[@marksavage]

Poldinho67slo when running it sucks the oil in as the pump pushes it so all normally goes in Start bike and take out the pipe and it should as you rev pulse out so you know it’s working and you should have smoky oil as you rev the engine so you know it is going in bud You could use a little tack to fit it in better and stop it coming out Mark

[@raul67slo]

Oh OK thanks mate! It was very smoky in the garage when I started the bike cold so I guess part of that was from the oil so hopefully all OK - I tacked the pin a bit with a screwdriver and it seems to be solid now. BTW the bike didn't start when it was cold before because the choke was always closing the holes in the carb (the metal part was always pushed too far out) so I took the auto choke apart and squeezed the little piston with pliers back to the normal closed position and that seems to have done the trick - I also adjusted the choke a bit by unscrewing the bottom part by a few turns so that the metal part of the choke just touches the bottom of the carb hole when it's warm - it starts perfectly now. Maybe you could look into it sometimes and make another video about auto choke - I'm sure it's a common problem that can apparently be solved easily. Thanks again and keep them coming! :-) Cheers mate!

[@mayanmuchnik5990]

Great vidoes!! I have a small question ?Do you know what is the original carb settings (the idle screw, fuel and air, and the niddle place) for Peugeot Trekker 50cc

[@marksavage]

Mayan Muchnik hi bud I have done many other videos on carbs Watch my other carb videos bud but start with 3 half turns out as in my last video Mark

[@mayanmuchnik5990]

I tried to put 3 half turns out and it make a bit of a change but i think my second adustable screw its the ?problem (the one that its a bit highr) so how much turns you turn it to original settings

[@raul67slo]

Hi Mark, I have a question about carb cleaning spray. Is it necessary to use this specific spray or is it OK to use "chain cleaner" or "break cleaner" instead? I've been to a few of the local stores and none of them have the carb cleaning spray - one guy told me to only put the carb and soak it in petrol (but I think this is mainly to clean the outside of the carb?). I guess I can always order it trough online stores but anyway I would like to hear what you think and thanks for all the great uploads! Cheers mate!

[@marksavage]

i stick to carb cleaner bud, Halfords or A1 many other car stores do it . other cleaner may have oils or contents that could damage the alloy carb or reeds if it gets sucking it to head! as for petrol well it sits in petrol all day any way lol it wont get it to the jets and may clean the outside like you say thanks for watching bud

[@raul67slo]

OK I got myself a carb cleaner - don't know if it's a good one or the rubbish one :-) Anyway I went to get my carb of the bike and I noticed that the fuel/air mixture adjustment screw is a weird one without any groove to be able to adjust it with screw driver or take it out. Have you ever seen this? I'd post a picture bit I can't here on KZbin. Anyway do you recon it's best for me to just leave it alone (and bypass it when I'm cleaning the carb) or should I modify it somehow, maybe try to drill a small shallow grove in it so that I'm able to adjust? I recon it's pretty important to get that part properly cleaned? Thanks mate

[@marksavage]

most carbs come that way so you cant mess with them. you can cut across it and then adjust but i would still clean the carb

[@manshaaaahuss]

Hi Mark, I cleaned my carburettor properly & put it back onto my bike and sprayed easy start yet it still doesn’t want to start!! What shall I do?

[@marksavage]

madz Rt if u have fuel getting in and a wet plug with spark and still nothing ? Try starting and keep the throttle open If it sort of spits / pops then you are going to have to look at the piston bud Mark

[@manshaaaahuss]

Okay cheers mate would you advice me to spray starter fluid into the cylinder? Would that improve anything?

Is there a trick or something to.get it on ? Also I have 2 pipes from the head which I have no idea where are they going. Thanks Mark

[@marksavage]

hi bud thanks for watching and well done to get it back together lol. ok front or rear shock, i have videos on them bud have a good look through my videos there are well over 50 and they do cover the shock . you may have to watch a few on front end and one day fix as i cover them there and i may go on about other items lol but they are on my channel was it front or rear. front is easy and as said there's a videos on it as for the rear you need to take off the petrol tank or lift it up one side again not hard bud but make sure there are the right ones as front and back are different the pipe are for the GRV for the exhaust, they don't need to be attached so don't worry . hope that help bud

Hi mark, I've got a peugeot vivacity 50 2t and im not sure what the problem is, when i start it from cold (using kickstart because it doesnt start with electric until its warm) it smokes like crazy for the first minute or so at idle or when i give it gas. When the bike is warm it smokes a whole lot less. Blue smoke if that helps? Please get back to me as ive no idea what it is. Cheers

hi bud so its 2t and burning a lot of 2t oil as the dont have engine oil, first what 2t oil are you using hopefully not cheap one , fuel , are you using e5 super of the e10 rubbish as in my video's and i have videos on both of these issue ... next and if oil and fuel are ok it sound like ring damage / piston and best to take head off and take a look at them and the head for scoring electric start we can deal with after bud

Hi Mark, Just a quick question. I ve got speedfight 100cc which I have manage to get it running with a carb from my 50cc speedfight. The one on 100cc looks like it does not want to work as its not sucking petrol from the tank. If you suck it manually,bike will start for a few secs and then cuts off. So as I said I have swapped carbs and its running ok but 50cc carb and 100cc carb is different when it comes pipes as on 50cc sucking pipe goes to manifold and on 100cc straight to carb. Am I right thinking that carb is faulty and needs a new one ? Thanks Mark

[@marksavage]

eNeRGetyk Power yes the 100cc carb air pipe goes in on the front so you maybe not putting it in on the right in pipe ! Or give it a service while off and make sure you have the right intake , if you have and after servicing it still.

Matthew Roberts that’s good news as for the speed maybe some of my other videos may help Mark

[@aaronvernon375]

hi do you know what size bolts is used for holding the carb because i have lost the longer bolt

[@marksavage]

8mm and its about 1" and a half but you can use like in my videos a bolt and a nut on the other side , its a bit of a bugger to get it on but will work if you use a longer bold bud you need to get it tight on otherwise it wont run

[@scorphkclark9122]

You need pics on the motor type i have thats the only way i or you can tell what year and model scooter i have.

[@marksavage]

as said google to find out what you have and then whats up with it

[@eddygray2345]

What carb is the best to buy for a speed fight 2 50cc

[@marksavage]

id always use a speedfight carb the Chinese ones are harder to set up wit the air mix being all the way in and they can run rich. I know they are hard to find and will be 2nd hand but if yo can buy one of them bud

[@travparr3538]

Hi could you do a video explaining how to run in a 70 kit properly, cheers

[@marksavage]

hi bud , oh dear have you watched many of my videos like this one ? kzbin.info/www/bejne/nn6xZY2KmdOlibc this is the best advice i can give for a 70 kit, i do have many other videos that may help have a good look through my videos on carb, upjetting mark

[@travparr3538]

I have watched many of your videos including that one, i mean like the best methods e.g. heat cycles ect

[@marksavage]

Trav Parr heat cycles ? You got me there bud Once fitted and running all done Did you. Up the plug temp , it will get hotter and add more 2t oil Mark

[@travparr3538]

mark savage heat cycles are where you start your bike from cold let it idle up to operating temp then let it cool down completely then re do this cycle you should always atleast do heat cycles after a rebuild Cheers

[@okeyjokey981]

What size is the mainjet ? Is it 50 ?

[@marksavage]

Is it easy to change my water pump spacer Mark?

[@marksavage]

S3ct1on Th1rt33n hi You have asked this before bud and I told you how to change the water pump but what is the spacer you are talking about and where is it ? I’ve taken of the pump before it’s not hard as in my last comment to you

[@SctonThrtn]

mark savage I was on another account and couldn't see my replies so I switched. I'm not too sure. I had coolant inside the side case and was told it was the spacer?

[@marksavage]

S3ct1on Th1rt33n sure the are sealed units bud Best Buy a new one but make you clean up the stator coil if water has got in there You will need to take it off , use my stator coil video on how

I think my speeake airscreew broke where could o get neew one?

[@marksavage]

hi if the screw is damaged and un-adjustable you can drill it out but finding a new one will be very difficult, how is the bike running ? if ok leave it as is, if not then you will need to replace

[@lauris4887]

@@marksavage its taking too much air in

[@marksavage]

Lauris so running weak ! Block a little bit of the air box so less air in bud but only a little Or replace

[@lauris4887]

@@marksavage thats what im doing . The broken screew is the reason it take air too much in?

[@marksavage]

Lauris if letting in air then yes bud Maybe use a bit of gum to part fill in the air mix to restrict the air in bud Keep filling in until the bike runs better

Mark,thank you

5:31 where does that pipe go?

[@marksavage]

I've many more newer videos since this one bud Theres over 75 speedfight videos to help That pipe is the air and goes into the manifold just in front of the carb After cleaning you need to prime the carb
