best carb clean video i have seen

[@rookie_homesteader9717]

Loved the video!! Simple straight forward and a little comic relief. Make more bud. I'd keep watching!!

[@kevinoneil9389]

Thank you so much for this. I just picked up a 05 PW50 for my son for his birthday next weekend. Its been sitting for years. Starts but don't run. I got the carb off, and the plug out. However the small jet seems to be stripped :(

[@ecran228e]

no prob bro any questions dont hesitate to ask...

[@flukey8516]

i just brought my daughter a pw50 08 model. mine seems starved of fuel. it just wont idle, unless your giving it a boot full. ill do a full clean of the carb & see how i go. thanks for the tips mate.

[@ecran228e]

Cheers :D

Having trouble getting the slide to go down once you hook up the throttle cable

9:10 Achilles last stand in the background !!! Ok, I'll give you a like!

[@SoyAweonado]

really good playlist on background actually

[@b1gdave514]

Ok i gotta ask, you say put 2 stroke oil in the tank..first how much, and 2nd i thought the oil reservoir at the handlebars took the oil and properly blended it..am i missing something? Im new to the pw50 world and just picked up a 05 thats been sitting for years

[@ecran228e]

It is not necessary to put oil in the tank that is only a precaution if the two stroke oil pump does not work which is rare. Yes the two stoke oil reserve is at where you mentioned and yes it properly blends. Just make sure you see smoke coming out of the exhaust once you start it :D

[@siggysea]

I have my daughter's old pw 50 I took apart to repaint the frame. thought wiring would be simple. was wrong. it's older and mostly wireing was Jerry rigged. do u know and could possible give me an easy diagram of the basic wires I need connected to make it run? thanks CJ

[@ecran228e]

www.weeksmotorcycle.com/pw50-wiring-diagram.html try this link as long as the magneto, cdi box and coil are hooked up and functional bike should fire. keep in mind any kill switches in line with these components that could be off or non functioning.

[@MrSCOOBY26]

What oil feeds into the carb as I've just bought my son a pw50 and that isn't there, where it connects too the carb its just got a bung on it?

[@Playboy27-l8t]

there should be an oil reservoir behind the front number plate that you fill with injection 2-stroke oil. If not then chances are the previous oil did the delete kit on it and you just mix your fuel on your own before putting it in the tank.

[@ecran228e]

Yes mix oil in your fuel at a ratio of: 32:1

[@cbecustomlandconstruction4896]

Helpfull video my man! Thanks

[@georgestoumbos975]

Love this video, question where the clear hose connects on the bottom of the carburator?is that hose for overflow?

[@ecran228e]

George Stoumbos yes : )

[@iagosilva926]

blz I'm from Brazil I have a bike like this and the start pedal stuck what could have happened

[@ecran228e]

The piston could be froze in the cylinder. If so take head off and put liquid wrench or some type of penetrating oil in the cylinder to free up wait a day or so then lightly tap on cylinder with a piece of wood. Be careful a little at a time be patient eventually it will come free.

[@iagosilva926]

@@ecran228e Thanks for the tip, I left it off overnight, it crashed by itself

Thanks Friend keep making video like this hug from Brazil

[@miketheboyle]

How do you remove the oil injector line from the carb?

[@lojp743]

Need this kind of video but with an engine rebuild. Spark plug keeps fouling, ugh.

[@ecran228e]

sounds like carburetor float could be stuck or jetting is to rich...

[@dreess8085]

"one of your old ladys stiff butt hairs, I dont care" LOL thanks for the video and the hilarious commentary. Keep riding brother!

[@ecran228e]

haha thx bro will do...

[@jamieloy9384]

"A flea's shit could block that"

[@reelmotivatedfishing1580]

do u think the oil injection block off plate would be better to do and mix fuel vs repairing and replacing mine haha

[@ecran228e]

Chad Neel I definitely think mixing your own fuel is better oil injection is convenient but not 100% reliable.

[@justinhanson4759]

Great video. I just recently purchased a pw50 for my son and it has an issue going on with the drive shaft. The rear wheel does not spin as freely as yours did when you turned by hand in your video. Any thoughts on the problem? Bad bearings probably or could it possibly be more than that?

[@ecran228e]

Sorry for the late response I personally have not worked on a PW50 driveshaft but I would imagine it would have some type of u-joint set up. These bikes are relatively simple and easy to work on check on line for PW50 drive-line schematics so you can get a better idea of what you could be dealing with. PW50 schematics are usually easy to find and very abundant through a Google search also don't forget get to check under the images category after your Google search a lot of people are known for posting PW50 schematics images.

[@ecran228e]

Hopefully you had it in neutral and the brakes are adjusted correctly ahahah... Its all good please reply with your solution in order to help direct anyone else that may have the same or similar issue thanks bud BRAAAAAAAP!!!

[@miketheboyle]

Good video BTW! Great job!

[@ecran228e]

thanks bud any technical questions dont hesitate to ask

[@miketheboyle]

See below comment... just wanna make sure she's pumping oil before I put it back together.

[@ecran228e]

easiest way to check if the oil pump if functioning is to pull the oil line off the side of the carburetor while the engine is running the more you throttle up the more oil pumps out I have never tested any other way thats why its important to mix some 2 cycle oil with your gas prior to first start. I'm sure there is a way to test the oil pump without engine running just haven't researched it.

[@miketheboyle]

I was stumped by the metal ring on the vacuum hose connected to the nipple on the carb. But I did see a way to check the oil is flowing. So think I'm good there,, just need to be careful not to break.... Thanks for the reply!!! Other issue I'm looking at is getting the dual throttle cables (fuel and oil) through the brass sleeves on top of the car to replace. They won't pull through the bends...easily anyway. Moto on!

[@miketheboyle]

Got the cable thing figured out...duh.

[@tackleberry933]

All stock pistons have that little hole or dot on top of them.

[@masonpalomo6758]

my float bowl drain is leaking gas from the hose whenever it’s sitting on the stand, any ideas ?

[@ecran228e]

Sounds like a combination of a leaking fuel on/off valve and float fuel stop valve or stuck float

[@josecabrera4052]

That’s what she said

Freakin Saaweeeeeeeeeeet

glad you liked the vid hopefully I covered something helpful..any questions don't hesitate to ask...

[@badboybubby69]

Mine runs backwards any ideas??

[@ecran228e]

Engines will run forwards or backwards depending how you initially rotate it prior to first ignition fire... *wtf is your kickstart backwards XD*

[@badboybubby69]

@@ecran228e Crazy I’ve never known it happen before! Done some research, investigations into the stator plate me thinks

[@badboybubby69]

I’ve sorted this issue, the after market stator plates are wired wrong, I switched the wires round on the ignition trigger coil and the ignition source coil. Now runs forward! Happy days 🙌🏻

[@mathewlocklear4643]

Why does the back tire want to keep spinning while its idling?

[@ecran228e]

Mathew Locklear could be that your idle is to high these bikes have what is called a centrifugal clutch meaning as you throttle up the clutch tightens up hence causing the rear wheel to spin if idle is ok then clutch maybe engaging to soon or at to low of a rpm. Some wheel spin at idle may just be normal as long as it is not causing the bike to move of coarse.

[@mathewlocklear4643]

When i get the idle correct the bike doesn't want to pull, stalls out and cuts off. Thanks

[@mlpdoctortardis]

my son's bike wont start and if I do eventually get it to start by putting fuel in with the spark plug it will only keep running when I tilt it to the left! not sure where to start

[@ecran228e]

Well this sounds exactly like what the problem was with the bike I go over in the video. Establish how long it sat and was not started if bike sat for an extended period of time there is a very good chance the old fuel clogged the 2 jets that are inside the fuel reservoir bowl at the bottom of the carburetor (jets appear as small brass screws with a tiny hole in the the center each one is numbered in size in order to meter fuel properly) these jets need to be cleaned out and all other ports inside carburetor must be cleaned out as well. After doing so clean out and replace any old fuel in the main fuel tank make sure there is TWO STROKE OIL in the oil reservoir and mix a little with the fuel upon initial start up just in case your TWO STROKE OIL PUMP is not working. hope this helps you check entire vid I go over all these things and if you have anymore questions dont hesitate to ask...

[@ecran228e]

also dont over look the fuel shut off valve located on the fuel tank those get clogged as well there is a very small filter screen inside this shut off valve make this your first step establish that fuel is actually getting to your carburetor before you get ahead of you project...

[@mlpdoctortardis]

thanks so much iv fixed it! all thanx to you!!! brilliant running sweet now! THANK YOU!!!!

[@ecran228e]

Allright sweet thats great I'm super excited for you and the kid thats awesome... Hey if you have a spare minute I'm curious what the problem was let me know your reply can possibly help out others with a similar problem (no matter how simple it could of been its still helpful to know) thanks and congrats with the bike..

[@mlpdoctortardis]

yeh sure all it was was a clogged up carb did what u did hay presto had to tweak with the throttle screw and runs sweet!!

[@bbullsj]

I got a 97 pw50 2 stroke and I can get it to idle but not have an throttle response. Pretty much all of the parts are new and I've checked everything I can. Any ideas? Here is a link of what it is doing. kzbin.info/www/bejne/n4bbXmqfpZpgZ80 It has a 60cc big bore kit, new wiring harness, exhaust, carb, spark plug, stator, kill switch, coil, air filter element, fuel filter. It has good compression, it's getting gas, no exhaust restriction (it's off in the video), I've tested the switch and I get good readings when I should and OL on my meter when I should. I'm totally stumped although there can't be anything left to try that I can think of.

[@ecran228e]

*well first off I believe your fuel filter is on backwards I suggest removing it...secondly is the throttle cable actually attached to the slide inside the carburetor? third check if its getting enough air from filter side...fourth is there any exhaust obstructions? please consider posting what fixed it for others to learn from ty :D*

[@bbullsj]

I have the arrow on the filter pointing towards the carb indicating fuel flow. The throttle cable is moving the piston inside the carb. I have tried running it with and without the air box (no change), the exhaust is off the bike so there can’t be an obstruction in that (it is also brand new)

[@ecran228e]

@@bbullsj is the needle attached to the slide inside the carb? Also two strokes need the exhaust pipe on hence the expansion chamber that scavenges excess fuel needed for thorough combustion...get a can of either and spray some into the open intake of the carb and see if the the idle goes up...something seems a miss with your carb...air -->fuel -->spark ...base on these 3 principles you are getting air and spark although it seems you are lacking enough fuel to power up the motor...if you have a big bore kit and a stock carb with stock jetting well there is your answer most likely...also make sure the new harness is correct and installed properly which im sure you have...just keep in mind what you changed prior to this problem and reverse engineer what could have caused this by deduction... keep me updated :D

[@bbullsj]

@@ecran228e Yes, the needle is attached to the slide inside the carb. I will put the exhaust back on and check it again. I sprayed starting fluid into the carb while it was running but got no change. I did it with the throttle not being touched and then fully opened. No change. If I was going to change the jetting, what would I need to get? I have never rejetted a carb before but I know there are different numbers for bigger and smaller diameters. It doesn't seem like any of the connectors on the harness could've gotten mixed up. Could this be a bad CDI controller?

[@ecran228e]

@@bbullsj if there was no change to idle when spraying either into the intake this seems like either the spark timing is 180 degrees off and/or not advancing or you have absolutely no compression which of coarse you should since its a new top end. this scenario is common when one burns a hole in their piston fyi

[@josecabrera4052]

Stiff ass hair works lol

[@E36hunter]

How do I take the air filter off??

[@ecran228e]

I believe there is only 1 single bolt holding this on. Remove bolt then remove air fiter housing then split air filter housing to find air filter element.
