bayou 220 carb tuning
im working on a '95ish bayou 220. it is a farmer's machine; no maintenance, not taken care of, etc.
i have it up and running, but it stumbles pretty good when you gently roll into the throttle to take off. if i get right on it, it will idle up and the bike will drive around pretty good. the carb has been apart, thouroghly cleaned, full rebuild kit, etc. unfortunatley, the pilot air screw is stuck in its bore, and wont come out. (wont turn).
any tricks to getting the stuck jet out? i dont own 1 can of any penetrating fluid, as i just dont dont belive they do anything at all. would that even have any impact on the stumbeling issue described above?

I don't know how penetrating oil will do on a jet that is stuck from corrosion, but anything to do with rust and penetrating oil is where it's at! WD-40 is great. Many times you can spray it on a rust bolt and watch the rust run off with it.
But onto your issue... If you have the carb stripped down with no rubber/plastic on it, then I would take a small torch and heat the aluminum that surrounds the jet for a couple minutes. Then spray some penetrating oil around the edges of the jet and see if she'll come loose. The heat should expand the aluminum some to loosen up on the jet a little, and the penetrating oil will suck in from the heat and help as well. Be sure and try and loosen it while the aluminum is still hot. Good luck!
