Have a 120 OMC "iron duke" straight 4 engine with a Mercruiser Sterndrive
Just pulled the boat out for the first run of the year. Wouldn't start and had no spark, so I change the points and condenser (points gapped to .019). After some fiddling I finally get it to start, albeit a little rough. Put her on the water and it runs fine for an hour or so. Pull a tube and run around the lake. Then without warning the engine starts to have a sudden power loss. Engine sounds like its "bogging" down.
What i mean is I will accelerate to speed, then the rpms suddenly drop off and I lose all power until the engine dies. Starts right back up, It will idle and do low speed fine but once I start to give some throttle it will go for a few seconds then drop off. If I am quick enough and pull the throttle back before the engine winds down then it stays running.
Then after dying about 10 times the engine would not restart until I unhooked the throttle linkage and manually dumped fuel into the carburetor while turning it over. Then it started back up again enough to limp it to the dock.
Thoughts?
