Is it possible that the reason my carbs are leaking at the air idle mixture screw is because the Main and Needle Jets are not the propper size that go on my R69S carbs. New jets were replaced but I did not look at the numbers when I received them. If someone is positively sure this could be my problem, then I will remove them from the cabs to check.

I just finished checking all the jet numbers etc in one of the carbs (the one that leaked most). All numbers were spot on!
