i have an OMC 350 that has a weird intermitent stumble, only when trying to accelerate once it works past a certain point it is fine. working the throttle back and forth seems to hit a sweet spot and it goes great. until you bring it back down and try to bring it back up....... fuel filter replaced/ carb rebuilt. no change.... thinking ignition ???

I just had a little episode of that same thing. I had knocked some connections loose above the oil filter while trying to get the crushed one off. I had put the wires back on but the connectors were too losse to stay put so it kept cutting in and out.

It was the same thing where if I played with the throttle it would be fine. I think it was that when I played with the throttle the connectors would move.


Easiest thing too would be to check and re check all your connections. Even check the spark plug cables and all that good stuff. Never know.
