I don't want to 'hijack' this thread, so Moderators do let me know if I should start a new one.
But on the subject of air screws for the off idle to low rpm range.
I'm having big trouble starting from cold, it will never kick but goes after a (sometimes lengthy push). Once running, I've noticed its very wooly from idle to around 3000 rpm, too much throttle and it wants to bog down, too weak a mixture? From 3000 to 12000 rpm its as crisp as a winters morning. Air screw setting?
A final point, once warm it'll go first kick, or by hand, with no throttle!
