Holley Ultra..Engine Stalls Hard Braking
I installed a new Holley 650 Ultra Double Pumper. Runs fine except I'm having an issue with the engine stalling on hard braking. I'm suspecting fuel slosh is killing the engine. I've lowered the float levels to the bottom of the site windows, raised the idle to 1k rpm, disconnected the PVC system, checked timing and checked the vent whistle. No improvements. I saw some discussions on-line about the bowl vent but also heard the sloshed fuel comes from the air bleeds? I had a close look at the top of the carb and noticed there wasnt a brass piece in one of what I think is the air bleeds -see photo. I looked at 2 other Holleys I have and they both have the brass piece in every hole. Might this be my problem? Fuel coming into the carb throat because this hole is unresticted? Anyboby have a Ultra double pumper they could look into and see how theirs compare?
