Proform 850 dialing it in closer
The bleeds in my 3 hole QF850, top to bottom .027, .027 and .032. Plugged the middle and left the rest open. Moved the IFR to the bottom and reduced the jet from .039 to .031 which helped my idle AFR immensely. Need to work on cruise then should be close.
Learned a lot at Racing Fuel Systems that Mattax links to.
