intake?

Those are the ones i'm talking about. The idle adjusting needles.

 

i turn them in all the way. then turn them out, i jus kinda learned to adjust timing and the carb by ear

 

You could be missing out on mileage and or power. If too lean you could shorten the life of valves or something... excessive heat.

 

its jus something ive learned to do cause ive never really had a timing light or anything around, ive checked it a couple times. i get it pretty freakin close

 

yeah they already have been adjusted.just need to set the timing a little better
