Hello there, i have similar 150cc died on me and it started to leak fuel out of the downpipe that is connected on one side and not on the other other i pressure i believe do i need to clean it is it clocked?
Thank you! If your carb has an O-Ring then you just need 1 between the spacer and the upper intake. Then you need a gasket between the bottom intake and cylinder head. Hope they helps!
@@connorjack3246 so if the black plastic (spacer) has an oring then you just need a gasket on the other side where there is no oring. Bascule you need a gasket where there is no oring. On both the top and bottom of the intake
@@slavsquad thx bro. Ill definitely give it a try. For now if I always turn off the fuel tap when I kill the ignition it seems ok. I guess it must be sucking enough fuel when Im riding to not notice.
Twist it off the top if your carburetor is like mine. Once you get it out if you want to remove it further, you have to compress the spring with your fingers and then pull the wire through the bottom. Once you compress the spray you should be able to see how to get it off the cable.
Some people got lucky with compressed air down where the fuel line connects but it doesn’t always work. You can still have dirt trapped inside. And eventually might make its way back into the Jets. It’s really easy to take apart and clean. That would be your best bet
Also if your carb has that bolt type thing at the very bottom. Should be like a 17 mm or something big. You can unscrew that and you’ll have access to the two jets. This is how you normally do it on a big dirtbike or four wheeler if you don’t want to pull the carb
Uh bro i got a Chinese carb from a pit bike just like yours and he cleaned it before i got it and he Said it's leaking fuel it's been a month since i got it so i said i clean the little jets and main jet was clean the little one that yours was clogged mine was so clogged up that you couldn't unclogged it with just air so rn I don't know if that fixed the problem
@@slavsquad i tested the float if that doesn't work then i need to buy a gasket it doesn't have a oring it has a gasket 😒 which makes my life harder to find parts for it
@@slavsquad brother It was the jet and they way of closing the damn thing I'm gonna add my 22 carb next week probably but my engine is burning oil should I put the 22 or nah?
It’s just factory Pitster pro forks and the carb is the factory mikuni carb that comes with the 140cc engine when you buy it. Same with jets. All factory I don’t know the size of the jets unfortunately
Usually screw it in 1 1/2 turns out. And idle 2 turns out. Start the bike. Turn the air to fuel in or out to get the highest/smoothest rpm’s. Once the engine is running its best you can then turn the idle screw out to lower the rpm’s.
Next time work smarter not harder!! U took the time to cover the shit with a bag when u could have put it on then washed the bike. But the video was helpful.

How many gaskets you got on the carb for the manifold?? Great video
Thank you! If your carb has an O-Ring then you just need 1 between the spacer and the upper intake. Then you need a gasket between the bottom intake and cylinder head. Hope they helps!
@@slavsquad so the black plastic bit with an o ring in by the carb does that have a gasket on that end too??

@@slavsquad yeah ok bro thanks for the reply 👍🏻 and what do you recommend on the valve clearances on a 120cc 4stroke
@@connorjack3246 my pleasure. I’d say .003 intake and .004 exhaust
Awesome o found the video I need!!
I'm taking mine apart now!!
Should I run Nibbi PE22 carb on a 140cc
Mine keeps falling off
What was your issue ??
My pit pro 140 does exactly the same thing. Leaks from the intake when standing still
Tighten the screw at the very bottom of carb. If it doesn’t fix it take it apart and do a full clean
@@slavsquad thx bro. Ill definitely give it a try. For now if I always turn off the fuel tap when I kill the ignition it seems ok. I guess it must be sucking enough fuel when Im riding to not notice.
@@LifeExplosion if it doesn't bother you then no problem!
@@slavsquad thats what Im thinking too! Stay gold bro
@@LifeExplosion thank you 🙏 you as well!
how to remove the needle in the carburetor?
Twist it off the top if your carburetor is like mine. Once you get it out if you want to remove it further, you have to compress the spring with your fingers and then pull the wire through the bottom. Once you compress the spray you should be able to see how to get it off the cable.
i tried this on my 125 cc china dirt bike but my carburator is still leaking and i did tigh in the flow screw but still leaks???
Where do you think I could buy another float needle?
Probably eBay would be most options or Amazon
Thanks so much now it dont leak all the time
Got my 155 h.o going but my carb is flowing gas into the motor, thinking the needle and seat at done
Carburetor is a frinch word for do not F*** with
Lol shoot
Best link for a carb on a 140cc
Is there a way to clean it out without taking it apart

@@slavsquad appreciate and I’ll give it a shot and take it all out and clean it good
thank u bro
Hey man does your carburettor touch the head of the motor ? cause i just put a new motor in and the carburettor that came with it touches on the motor
Mine never touched but were close. Make sure your using both spacers on lower and upper intake
@@slavsquad yeah i have the paper gasket on the button of the intake then the rubber spacer between carburettor and intake
@@pablo-eskibah3441 might need another spacer on the bottom
will your jets still work if they’re a little bit bent
In my experience carbs are very picky on these and it would probably give you issues.

It might fix it. Could also be a float problem. Jet clean fixed mine

@@georgemixalakis3724 yeah that’s weird. Should be a oring
@@slavsquad brother It was the jet and they way of closing the damn thing I'm gonna add my 22 carb next week probably but my engine is burning oil should I put the 22 or nah?
@@georgemixalakis3724 gonna burn oil regardless so why not
Do both those tubes going downward connect to nothing?
Yes they just hang there for extra fuel to come out or when you flood it
My spills gas too should I do this ???
Yes!!
what forks are those may i ask? looks like a 140cc i got the same carb and do you know what size jets are those? tysm appreciate it!
It’s just factory Pitster pro forks and the carb is the factory mikuni carb that comes with the 140cc engine when you buy it. Same with jets. All factory

@@slavsquad it’s all good no worries ok i’m bouta order some inverted forks for my 140 build. appreciate your help!!
@@AF.256 my pleasure! Inverted forks = 👌🏻👌🏻
How many turns does the air screw have?I have the same motor and carburator but my pit bike works badly
Usually screw it in 1 1/2 turns out. And idle 2 turns out. Start the bike. Turn the air to fuel in or out to get the highest/smoothest rpm’s. Once the engine is running its best you can then turn the idle screw out to lower the rpm’s.
@@slavsquad OK thanks
@@slavsquad do you have stock jets in yours the 107.5 and 15 ?
@@mikalblock4389 I just run the factory jets. Not sure the size off the top of my head
I didn’t do it
Haha

True. Oh well ool
could this fix the fact that my pitbike smokes
No
You need piston rings or head gasket
