New to this board, looking for any help.
I have a 1990 OMC 225HP Looper.
While out one day I lost throttle. I took it apart and saw that I must not have tightened the clamp down enough after my last adjustment. I put it back, but after this we were not able to get the thing to fire up again.
After getting towed home, I saw we had zero spark on all cylinders. So I replaced the powerpack. That gave me a very weak spark. I tried new champion spark plugs and gapped them at .030, still no luck.
I disconnected the kill wires, the yellow wire from the stator, and checked all resistances and voltage. Everything checks out. I even get a nice 150-200VAC while cranking from my brown to brown/yellow wire - which is why I now believe the stator and flywheel and magnets are fine.
The coil connections look nice and the spark plug wires look fine.
I do have spark. It is a very weak yellow spark, not a nice blue one you would expect to see. The plugs get wet easily and I can get the engine to start on ether but cannot get it start otherwise. I have charged the batteries as well - so I there is enough juice to start it.
I think spark dwell timing maybe got knocked off? Or a trigger problem (although I get a pukse)? Or a ghost?
Sorry for the long post. But there are lots of details.
