Step 1 Tools used

Allot of motorbikes or quads have been sent to the shop to be fixed and in the process you spend allot of money. When in reality you can fix it youreself for next to nothing. And worst of all you need to wait up to a few weeks for the bike to be finished.

great isntructable! I only wish there were more lie this... I recently picked up an old atv that was flood damaged. It still turns over but its pretty rough... I'm going to do my best to fix it up paint it and sell it.

It should be mentioned that screws in carbs are generally made of soft alloys. Dont overtighten because its easy to strip a screw.

[nibbler125]

i also said in the instrucable to not overtighten anything

[nibbler125]

ya its important that on anything like this it shouldent be overtightened

[JerryMopar]

On all the cycle/atv/snowblowercarbs ive done, i always replace the screws with allenheads (socket-cap)!

you may want to also clean the needle/slide and the pilot jet screw (REMEMBER THE FRIGGIN' POSITION OR YOU'LL MESS IT UP) You should probably make sure the float needle and its 'home' are clean enough to eat off of because if it seeps at all it will end up going into the combustion chamber then leaking into the oil

normaly i just spin the slide slowly untill it pops into spot. but i have taken apart this carb many times. so its prettymuch natural to me
