In the 25 pic make sure the grey o ring sits in the groove in the carb when you put it back together.

They do make a quick adjustment tool it can be purchased at rockymountainatv.com

Bad thing is you need really small hands to use it.

Best thing is to adjust the mixture before re-installing. If you notice any hesitation then re-adjust. It's a pain in the arse, but follow the rule of three turns on the mixture screws......It's going to be close unless you live in high altitude areas.

If you bought a kit, just follow the kit's instructions for high altitude applications.

Higher altitude = thinner air, thinner air will richen your mixture.

So you should be on the lean side of recommendations made for sea level bikes.

As Brian said, your kit should have recommendations for high altitude operation. If it doesn't check the company's website or call their customer service line.

Photobucket is trash now, use something else.

Re: Carbs 101....Jetting...cleaning....everything you need to know about carbs

looked at a clean 04 used other day it starts real nice and easaly and mine wont. I need to clean the carbs and check jets and thangs anyways so I thought this would be one cause of my problem. I have questions. I have read the carb thread and study it good. few questions.

Im not sure what jet i have 100% i got a power kit from advantage performance with my dmc allen exhust it came with k&n and recharge kit and i beleave a dynajet stage 1 jet kit.

How do I rejet and set the screws? what type of messureing device will i need if the job requires one?

Also how should i re set or adjust my air/fuel screw if needed? I exsperiance delayed starting time and here some pluff pluff sounds sometimes when i turn it off which sure could be related to valves are even the one way clutch?. How do i know if it set to high or low? and how many turns should i take at a time to check if it`s right or to get it right lol. I have`nt adjusted my valves yet and need to but dont have feller gauge yet.

My most importin questions are about the jets and the air/fuel screws

All the above worked to perfection...!!! VERY HELPFUL.... BUT when I tried to adjust the fuel mixture screw it would NOT turn! ended up stripping the head off the screw and could NOT get it to break free... Ended up trying "easy outs" and still could never get it out... pretty sure I ruined the whole carb. Just for future reference is there some easy way to break that screw loose? I am SO MAD!!!!
