Carb Cleaning Question

[mtownjake]

This is my first attempt at using a forum to get technical answers. I have to say the GS Carb Cleaning series is excellent. I removed and dismantled my BS series Mikunis from a recently acquired 1980 850G. I was unable to dip the carb bodies because I could not successfully remove the pilot jet or the air screw. I couldn't get the pilot jet out because I simply could not come up with a screwdriver small enough that would work. The air screw appeared to have been exposed to the elements for some time and after some fairly forceful attempts at getting them to even move I quit before I hosed the slot. Any tips for getting stuck air screws to come out? What about tool reccomendations or should I plan on making my own?

go to sears and find what you need.

soak the unhappy screws in pb blaster for a few days and hit them with a heat gun. You were smart not to force the screw they both strip easy, bring a carb with you to sears and see if you can find a screw driver that fits snug in the slot.

Good advice here. \\/ Never force the screws. Heat works great as well. I was having a heck of a time getting the slides out of my VM carbs due to varnish gluing them down. Soaked for several hours in carb dip but they were still stuck. Took my heat gun to them and after a few minuets the slides literally fell loose on there own. :-D Surprised the heck out of me but in a good way.

I'll give-em a good soak in Chem-dip and then apply the heat. I'll report back and let you know the results. Thanks.

I'll give-em a good soak in Chem-dip . . .

I soak them for just about 24 hours for routine cleaning,
so you might consider at least that much for your "stuck screws" problem, as well.

Hey howdy hey!

Mr. mtownjake,

I'm sorry for the obvious question. Have you had a chance to check your valve clearances? Carb cleaning and tuning is most effective when the valves are in spec and the airbox, carb boots, etc, are sealed with no air leaks.

Thank you for your indulgence,

Just in case? I have found a good source for pilot and main jets any chance that I can find replacement air screws for these carbs?
