Large scale carb tuning Pt2

[@wigesworld420]

10 years later you’re still helping people (me) when I get home from work I’ll be trying your method. Thank You for taking the time to do this video.

[@Poopdogsays]

No problem! Hope it helps!

[@Resurrection9]

Best 1/5 scale tuning video on KZbin, so easy to do. So much easier than trying to listen to what the engine is doing in the field.

[@paulingram9787]

Good info. Matte if you need to see his hand turn screw you are missing the point. This is all about using your ears. I will never understand why people feel the need to criticize every little thing someone takes the time and effort to try and help others out and instead of being thankful they have to crap on it.

[@Poopdogsays]

Paul Ingram Thank You, not everyone appreciates the time it takes to put this shit up for free! If you guys notice there is not one single advertisement on any of my vids! So I'm not making a penny to do this, it;s just for all of you guys. So yeah there are some mistakes, but Paul gets the point of this vid! Thanks Paul!

[@Casey6996]

Gday mate. it is still a good video but to see what he was doing is also important just like the sound. It is also a good idea to tell people what is the high and what is the low needle. specially for people that just start off in the 1/5 scale and tell people that most walbro carbs use the same setting. I did not hear him saying about when you have reset to factory settings after you made a mess of the adjustments,,, how many turns you have to screw it out. that is also very useful for beginners

[@GG7162]

This was of great help. I really appreciate it! Hands down the best tuning video Ive seen. Finally I can tune my 32 cc Hsp truck.

[@Poopdogsays]

Good to hear, thanks for the nice comment! 👍

[@Poopdogsays]

Thank You!

[@rickc2335]

awesome info bud, this is my first 1/5 scale and wasn't sure what i was doing until i saw this vid. thanks

[@Poopdogsays]

I set it by ear, set it so the clutch engages after just a short rev. If you set the idle too low, it shocks the drivetrain when the clutch grabs and trashes drivetrain components.

[@SvanbergSimon]

thumbs up. because of this video i can tune my 1/5 scale monster truck. much appreciated.

[@Poopdogsays]

No problem, glad i could help!

[@geolopez914]

Much respect on making this video...it's people like you that make the difference! I'm having a bit of trouble myself turning my FG, just put in a new plug and it's acting up....need to reset my jets. My question is how dose someone know what the proper idle screw adjustment is? In conjunction with the H speed & L speed?

[@soundwave_9568]

Both videos have helped. I still struggle with it but still I keep hammering at it

[@reubenmedhurst9118]

This really helped me understand this topic, I'm new to the petrol rc stuff and this helped me understand why my engine sounded so shit! Great advice!

You're very welcome, im glad i could help.

[@Chris10rx]

I'm bout to try and fire mine up again. See if I can get it balanced right and all that cool stuff. It's dirty as hell and I hadn't ran it for a good 7 months. Just put 100% octane with full synthetic two stroke oil from craftman. Got a fresh plug in there as well

[@HeyGuysItsRob]

Best tuning vid I've seen. Thanks for posting it

[@TheMadbashtone]

thank you so much.. DAMMIT i knew there was a way or system to addjusting the high n low.. i also feel the best tune is listen and do what the motor tells u it needs.. now i know what to listen for so big thanks....

[@Poopdogsays]

You can if that makes you feel more comfortable, but I usually don't. I lean the needles until I don't see an increase in performance then I back it off buy a 1/16th to 1/8th depending on the throttle response. I'm glad you liked them and if there is anything I can do to help, feel free to leave a comment and I'll do my best to help. PDS. (Trip.. on the forums)

[@byrd5873]

Great videos. I am having problems with my gas motor. As far as the high and low go I am fine. The idle screw is what I have a question about. Where is a good starting point?

[@Poopdogsays]

Sorry to get back so late, but yes you can adjust carb needles on the second tank. With these motors there really isn't a "Break In Period" like there is with a nitro. The tolerances in a nitro motor are much closer than these motors. Run the car around for the first tank at a moderate speed to get the gears in the gearboxes seated in and then go beat the snot out of it! Have fun, PDS.

[@jamesoldebeken3625]

Helped a lot and made things clearer

[@Poopdogsays]

Sorry for getting back to you so late, I just saw your question. I would start with the hs and ls at around 2.5 turns out from fully seated, that will get you started. This will be a bit rich, but it's better to start rich and lean it out than to start lean. Good luck. PDS..

[@dionmedlen1667]

Thanks man just got all the info I needed in one video. Cheers buddy thanks

[@andygrosv3246]

Great help and very informative 👍🏁

[@kevinwaho7657]

Hello.. all the way from new Zealand! Awesome video. I've been struggling to tune my Zenoah g320 on my losi 5t. Its already destroyed 2 new plugs and I don't understand why. Car also sounds like shit.. Ive tried to refer back to the factory settings of 1 and half turn and 1 and quarter turn. Car still struggles to start, when it does it sounds like shit, even after adjusting the idle screw. User manual states don't go more than 1/4 turn from factory or engine will damage, I know the turns on the needles are small increments but I still can't seem to get it right.

[@Ryan-gf3jf]

Great Vid !So tunning ur high screw u just listen to the highest rev and then back it off? correct ?

[@petelampasone2234]

The other big screw below high and low is the idle screw correct.?Thanks very helpful.

[@Poopdogsays]

Correct. You're welcome.

[@jorgefigheroa77]

Nice video....i will be installing a 990 Walbro carburetor on my rampage XT...any tips.?? or needle adjustments out of the box??THX..!!!

[@philkennedy1105]

So what you did was get it to it’s peak scream then back off a touch ? I got told years back to tune that way ? 👍

[@MrBankertke]

At the end of your video you mentioned that you are using 50:1. Should it be closer to 25:1? I am new to my HPI Baja 5B. learning. thank you

[@Poopdogsays]

I personally run 50:1 klotz oil in my 2 strokes. Anything from 25 to 50:1 is fine. I run a lean oil mix because i hate oil goop puking out the tailpipe. Always run a good oil, no weed wacker oil from lowes. Oil is cheaper by the gallon from a powersports store, snowmobile oil is great!

[@26bitgaming25]

how do I set the settings to stock??? and by the way grat video!!!!

[@warrenfranklin6281]

50:1 is less oil but all good,anyway good video mate simple and straight up.

i love da big cars

[@richardmoore5919]

Good video, I learned to tune two-stroke engines by ear as well. My two comments are: 1) 25:1 fuel ratio NOT 50:1. These engines run at high rpm's, and need plenty of oil. Otherwise you sacrifice how long motor will last. (Two tanks of fuel versus 20 tanks of fuel.) 2) never run a two-stroke engine that lean at full throttle. Unless you plan on immediately doing a top end rebuild, or you are racing and big money is on the line.... That two-stroke engine is not meant to run that lean.

[@Poopdogsays]

Thanks for the kind words Rob!

[@cruzy1969]

GREAT HELP THANKS AGAIN

[@paulxray2782]

Thank you very much this is how I would tune but with all the other ways I thought I should do it there way till I saw your video. This is the most common sense way way to do this. Just ;ike tuning nitro rc planes that I flew for years.

[@Poopdogsays]

Yup, that's how I learned as well!

[@dylanshenk446]

I'm having an issue to where mine does not want to run unless I throw alittle bit of starting fluid in then itll run for a few seconds. I think it's not getting gas but I have the high and low idle screw set to factory in the book and it's not staying running.

[@Poopdogsays]

Dylan Shenk where do you have the idle screw set (the big silver screw) sounds like the screw needs to be turned in a bit. Try turning it in 1 full turn, then restart, but make sure the back tires are off the ground so it doesn't take off on you. Or just take the wheels off.

[@jimson123]

Very good video !!

[@vasiletomazian7417]

Tks...nice vid.Where you get the ..."stand" ? Tks in advance for reply !!!!

[@Poopdogsays]

vasile tomazian Home depot in the tool section by the saws and hammers, I think it was like 25 bux. I put some of that rubber drawer liner on the top so my car doesn't fall on the ground. I used 3M spray adhesive (from an auto parts store) to stick the drawer liner down permanently, it works pretty well.

[@djpuppy69]

your running 50-1 ...i have the same redcat 1/5 buggy i run 25-1 should i start useing less oil? im trying to tune my buggy for winter running -20c..when the engine gets to temp it will no longer run unless i keep priming it..its a stock 30.5cc cy engine..

[@nitroneal48]

it helps a lot

[@tonytaylor5397]

A video of your hand ?

[@TheKemenb]

Great video! Today I tried to run baja in snow and had to lean it to 1 1/4, factory settings are 1 1/2. I'm not very comfortable doing that. My question is how to tune engine in winter?

[@Poopdogsays]

Klemen Bizjak Sorry it's such a late response to your question, but run it richer in the cold and run them leaner in the heat to compensate for the density of the air. The colder it is the more dense the air is and the opposite is true for hot air. Don't be too worried about needle settings because all engines are different and require a slightly different amount of fuel, then there's the temp, humidity, barometric pressure, blah, blah, Listen to the sound of your engine, it will tell you what it wants.

[@turbooomann]

I have a 32cc engine on my redcat rampage mt, I installed a reed valve but now when I hit the throttle it chokes out and cuts off, I have to ease on the throttle...my settings are all off! can you tell me how many turns out on the factory settings it should be so I can start off fresh please

[@jb845]

I know this video is old but I'm new to the large scale hobby. My issue is when I hold the throttle my rampage dont move unless i full throttle it. Then after a few min it shuts off on me. What is wrong? The brakes arent locked up.

[@Poopdogsays]

Change the spark plug. The torch plugs redcat supplies are junk. Ngk cmr7h (3066)

[@Poopdogsays]

Matte Edström Read Paul Ingram's comment, he explains it.

[@jasonmclaney8971]

50:1 fuel ratio? Redcat states 25:1. how has the motor held up with that ratio? And thanks for the vid, good stuff...

[@Poopdogsays]

Jason McLaney I've been running 50:1 for 10 years on all my large scale cars, it works for me. If it makes you nervous to run that lean on oil then keep it rich, it won't hurt it to have more oil.

[@javiergil8228]

Hi can u give me the settings so I can turn on my truck please for the low and high needle tanks

[@hallobyebye699]

I got one question regarding the fuel, why do you run Kermit on 50/1 ?

[@Poopdogsays]

Because ive always run 2 strokes at 50:1 anymore oil and it smokes like crazy till it warms up, then any unburnt oil leaks out the exhaust onto my floor. I only use good oils though. I prefer klotz or polaris snowmobile oils.

[@kevinwylie9167]

I've got a king motor 30cc if the power in the servo battery is really low will it start

[@Poopdogsays]

Yes, but i would either take the wheels off or raise the car up off the ground. The power to fire the spark plug is generated in the coil under the pullstart. You do not need a receiver battery to start the engine, but if the engine starts and you dont have control, the car can take off at 50mph...

[@hurdgaming]

My idle screw being out of whack will that prevent my RC from running? I can't get it fired up I pulled on it for about an hour trying to just get it fired and nothing.. how many turns out should the idle screw be ??

[@Poopdogsays]

Start at 1.25 out on both screws, that will allow it to start. Pull the spark plug and check for spark (i have a vid on my channel explaining how to do it) if you get spark, pour a tiny bit of fuel down the plug hole. Reinstall the plug. If it starts, then you have a carb problem. If it doesnt start its an ignition problem.

[@Poopdogsays]

Turn the big silver screw out until it doesnt touch the throttle lever. Then turn it in until it starts to open the carb. Once it makes contact, give it a half turn or so. Make sure when you go to start the car the wheels are off the ground so it doesnt take off if the idle is too high!

[@hurdgaming]

@@Poopdogsays thank you very much I will try this tomorrow and let you know how it goes ..

[@Hellcat2040]

Question im running a 40:1 gas is there any way I can tune it with the gas I already have

[@Poopdogsays]

Yes, you can tune it the same way as i do in the vids. I just dont like all the excess oil drooling out the exhaust pipe when i store it. 40:1 is just fine. Make sure you run a quality oil!

[@woodysgeekchannel2204]

My car is always a pita to start. Is there any secret to get it started in 2-3 pulls? Is this a problem with not having the low speed needle set properly?

[@nathanaelbas5289]

Could be your idle screw is not set well to open the carb wide enough to start it off in 2-3 pulls. If you need help let me know I know how to tube these to perfection

[@woodysgeekchannel2204]

Nathanael Bas Thanks, I will give that a try when I get it all back together. It was time for some deep cleaning.

[@nathanaelbas5289]

Np, if you've ran it for a long time now u should clean the carb with some wd-40 and if non of the above works I can only think off a dying engine

[@electropalsceo]

[@camarojames1]

Hey brother I have rampage Mt stock and every time I hit brakes truck turns off any ideas on what it could be thanks.

[@Poopdogsays]

The idle screw is set too low. Adjust it so when you hit the brakes the carb doesn't close. The trim on the transmitter (controller) is not how you set the idle speed. Adjust the big silver screw (idle screw) in until you hear the engine rev slightly, then hit the brakes and see if that solves it.

[@friscoHub415]

I have a redcat chimera and on stock needle setting it will not start it was working but I tried to tune it and now it wont start any help would be appreciated....and it's a month wait at rc shop

[@Poopdogsays]

The first thing i would do is toss that sparkplug that the redcats come with, they are junk. Buy an ngk cmr7h (3066) and retune. I bet thats your problem.

[@javiergil8228]

I have to do this on my truck but I have to go somewhere were they not homes cuz it don't have muffler so it's very loud

[@Poopdogsays]

You need an exhaust. It is next to impossible to get it tuned w/o one. The exhaust works to push the intake charge back into the cylinder and without it the intake charge just sprays out the exhaust port. Google "2-stroke exhaust fundamentals" it will explain the operation of a tuned pipe. Plus w/o a pipe or exhaust of some type the piston will suck in alot of dirt and destroy your piston and head. Put the can back on it.

How can i tell if my carb is no good on my rampage xt

[@mnsportsguy1978]

My Rampage won't restart after I shut it off. Any ideas?

[@Poopdogsays]

Is the kill switch button sticking in? Where are you carb needles set? Richer is better than lean. Usually these cars dont want to start when hot because the fuel cap doesnt vent.

Would u wreck the car or gearing revving it out like that with the wheels spinning freeley??

[@Poopdogsays]

It won't hurt it revving it with the wheels in the air.

[@Casey6996]

you can explode a tire ,,they start to look like a Pisa cutter, but he would have put packing tape on the inner liner that also make your tires last longer

[@TomOteri]

This is a good tuning video. I even hit like. However you mentioned your running at 50:1... That car stock, should be at 30:1 max (at least now it is in 2014). It could have been different a couple years ago BUT if your watch this now we actually run at 28:1

[@TomOteri]

It should be fine, you can't hurt the motor with too much oil, you just may foul the spark plug more easily. I use racing 2-stroke oil made for dirt bikes. I would NOT use oil that is meant for weed whackers and chainsaws.

[@Casey6996]

+e mad If you want the best oil for 1/5 scale engine I recommend Maxima castor 927. It is the same most the pro gocarts use I have a modified rovan with a 29 cc rcmk engine in it and use 25/1 mixture and my plug last around 9 months but the I only use it 4 to 6 hrs a week besides my nitro 1/8 and electric slash 1/10 scales

[@supernaturalunknown9451]

[@makerofmanythings8447]

You should take your exhaust pipe off and see if your piston is scorn. that would mean you are losing compression. If you are getting gas and have a spark this is likely your problem.

What oil do you use for your air filter

[@Poopdogsays]

I buy dirt bike air filter oil from my local motorcycle shop. Traxxas air filter oil is good stuff too, but these big filter take about 1/3 of the bottle to oil it. I tried the duratrax a/f oil, but its too thin and isnt sticky so i cant recommend it.
