I Cannot get more than 2800 rpm out of the 75 hp force. Checked stator and replace 2 bad cdm's and all 3 spark plugs. Engine starts easy runs good at lower rpms but does not go above 2800 rpm under load. with No load can rev to 5500 rpm and higher. Original problem was that going full bore when engine quit. tried to restart and had a dead short. Retried and it started but no power . Went to the manual checked stator and cdm's 2 were bad diodes were fried. Should I replace the 3rd module or look elswhere??

#1 cylinder 118 psi#2 0 psi # 3 120psi
Seems I have a problem with #2 cylinder
Got the feeling it isn't anything simple like a head gasket:mad:

Forget the decarb.
Pull the head and inspect.
Running it may cause additional damage, and a decarb won't bring back a cylinder from "0".
