probably going to need to open up the power valve restriction holes a little, but I would certainly talk to the carb builder before breaking out the drill bits.Kind of a vague question.. but on a blow thru carb
what would cause the WOT to lean out?
on my nephews boat he can get the air fuel ratio
almost perfect from idle thru cruise but when he
opens it up to WOT it starts leaning out.
fuel pressure is 7 psi at idle, 12 psi under full throttle
5 psi boost.
I know its a Holley by lance patton, (yes he is going to call him) but I'm curious what can cause this.
if he jets up it still leans out under full throttle.
from the dock it sounds like its missing slightly
when it leans out.
here is his target #'s
Idle 13.5 to 13.8
Accelerate 12.2 - 12.5
Cruise no load no boost 13.0 - 13.3
Cruise with small amount of boost and load 12.5 - 12.7
WOT 5 + lbs boost 11.8 - 12.0
everything is on target but his WOT it starts climbing above 12.5.
