1995 115hp. Motor is the 2+2 type. Runs pretty good and starts on the hose pretty easily after warm. but it is hard to start after it cools down or when in the water. Compression is 132 on all cylinders after warmed up. Spark is blue on all. Idle to wot is good. Oil injection currently in place. Just got motor and I wanted to make sure oil injection was working so I marked it to see if level dropped enough to show a functioning injection system. but during this i have ran 50 to 1 premix in the tank so im sure its running rich.
A couple of things that are bugging me:
-Engine pulses back & forth during different rpms near WOT by about 50 to 100 rpms?
-I heard the fuel line making a clicking noise and i grabbed it and it felt like a pulse?
-also, the primer ball will rev the engine when i squeeze it hard enough.
I thought i heard some knocking/ticking at mid wot but couldnt tell if it was in the midsection, the mounts, or power head. It didnt lose power or anything though. Also spotted water coming through the midsection gasket. Can there possibly be a bad cylinder or piston if it has perfect compression?
