I'm having problems with my port engine (1985 Crusader 305ci). It idles ok, albeit a little rougher than normal, but relatively smooth. When I bring it up to RPM say over 2,500 it gets a vibration that feels like a slightly bent prop. Doesn't have near the power it used to either. I checked the prop and it looks unscathed. Furthermore if I rev the engine in neutral I can feel the vibration so it doesn't appear to be a running gear problem.
I just had the stbd repowered. Before the repower the port ran absolutely great. But now it's running like crap. I'm wondering if the mechanics stepped on something (pinched plug wire?) or got something wet (ignition?) while they were replacing the other engine. I plan to replace all spark plugs and wires tomorrow, maybe the coil too as it's old and see what I get as all of this is easy and due anyway. I have an extra carb I can try but this doesn't sound like a carb issue does it?
I know this isn't a lot of information to go on but you guys have always been very helpful and I was hoping that maybe you could suggest a few other things to check.
