HELP
 

ok so i was adjusting the screw behine my afc housing where do i need to set it it at

the "smoke screw"?

what screw are you turning? The one on thr very back of the AFC housing?

Yes the smoke screw

that screw is ment for a fine adjustment of the afc diaphram.

Whats too much and too little do pros and cons

too much is tons of low end smoke to little would be not enough low end fuel

Thats screw controls the rack when the boost has not come up enough for the afc foot to take over.
