89 110evinrude outboard

[89rudeness]

got a problem

started with an overheating problem, had to R&R heads to replace rubber insertes around cylinder heads, after repair now it falls off around 4000 rpm unless you pull back on throttle, sounds like fuel issue, but has new fuel pump, lines, bulb, carbs rebuilt, check compression, 100psi each cylinder.

have any ideas, thanks

100 psi is a little on the low side but that could be a comp. guage issue.

Same heads? Correct gaskets?

Are you sure your carb butterflies are opening all the way and the timing is advancing all the way (synch and link)?

Did you check for spark on all 4 plug wires when it starts to fall of?
