I want a mixture screw that I can adjust with my fingers instead of a screwdriver. Can anyone tell me where to get one for a 1998 big bear 350 2wd? Or can anyone tell me the mikuni model number of the carb?

Thanks in advance

 

The question is, why would you need to constantly mess with the idle mixture screw? You are not supposed to alter them at all. If extensive tuning has been done, or you are running at high altitude, you may need to alter this screw. Once set for this, it won't need altering again unless altitude or tuning changes again.

 

The big bear came from an elevation of 500 ft and is now at 4500 ft. It has been sitting for a while and it seems that every time I get it adjusted good it changes after an hour of running. I don't know if the screw is actually moving or if I'm slowly cleaning gunk out of the jet or something. I am aware that it shouldn't need to be adjusted after it is tuned in but I'm getting tired of burning my knuckles. It would be worth 20-30 bucks to me to have the hand adjustable one if it exists. Hopefully someone on here knows of one.
