So Im going to be working on a buddys 2006 Grizzly 660. He says that its not getting fuel through somewhere and it keeps backfiring and wont idle steadily. He says it doesn’t really accelerate and then sputters and dies.

So Ive never worked on an ATV before as far as mechanical, but it sounds to me like an issue with a plugged fuel filter or a dirty carb. Ive done a lot of automotive work, but never anything with a carb, although I understand how they work. He ordered a rebuild kit off of amazon and ill rebuild it for him.

My plan is to dis-assemble the whole carb while taking note of where everything goes, then cleaning it all out thoroughly with carb cleaner, then rebuild it and replace all the seals, o-rings, and jets.

I just wanted to know if there’s anything in particular I need to know about replacing the new parts and in the entire process that would keep me from messing anything up. It looks pretty straight forward, but I know the jets are supposed to be sensitive as far as how tight you need to turn them. Also the idler and air valve. Any input would be greatly appreciated.

Also, Where is the fuel filter located? I figure Ill change it out while im at it.

Thanks!
