Quote: sure seems like alot of slot for only 2 turns of the idle speed screw. Yeah I'd clean the carb thoroughly & continue on
It does to me too (hence my surprise at discovering this). When I start cleaning up the carb tomorrow, what I'll do is turn the idle set screw completely out so the throttle is slammed shut, and check to see how much transfer slot is still exposed (if any). Then I'll turn the screw back in until I see it just contact the stop and count the turns needed to position the throttle so a 'square' of the transfer slot is exposed. That should turn out to be < 2 turns. If not, then I must've screwed up checking the turn count to begin with .
David,out of curiousity,how are you adjusting your idle speed and your mixture screws ?
Here is an AVS that idled at 800 rpm and worked perfect.You have way too much transfer slot exposed.Like I said before,bump up the timing,adjust your idle speed then your mixture screws.You will have to adjust both mixture and idle screws more than once until you get it right,one affects the other.There is no set in stone amount of turns on either adjustment,just a starting point,adjustment is whatever your particular engine requires.
