so i have been trying to solve a no cold idle issue. i

have a new afm so i have been playing with it. i
noticed this weekend,while i was setting the timing,
that leaning out the mixture, or using that 7mm?
adjustment hex screw on the afm(clockwise),causes the
idle to pick up...? can anyone tell me why that is
happening? the opposite happens when the mixture is
rich, idle go's lower and runs rough.
 i got the van to idle by itself, by playing with the
afm and throttle adjustment screw. it would still die
if i rev it up and let off the gas, or it will run as
long as i keep my foot on the gas, until warm, then it
will run just fine.
 i'm just wondering about the mixture, cause right now
i would think it is running pretty lean, only 1-1/2
turns out from the bottom. it seems to run much better
the leaner i get it, like it will more than likely run
well if i close that afm screw all the way down. just
worried about burning a hole in a piston i guess, as i
have read here that can happen. any constructive
thoughts appreciated.
