Both of my engines surge from 3200 to 3800 RPMs. When I advance the throttle and the 4 barrels open up they accelerate great.
Background:
1989 Wellcraft St. Tropez
Two new Gen IV 7.4L long blocks
Original intakes
New quadrajet carbs
new exhaust
new ignition components on old distributor bases
Original ingnition modules
new fuel pump on P engine
P reverse and S standard rotation
timing set on each at 10 BTDC
I originally thought that I had a fuel delivery issue but the engines perform great once the secondaries open up.
Ideas on what to try...???
