I have a 98 Moomba Mobius and the engine sounds like it's missing at one particular speed. It's happening when I shift from neutral to the slowest speed in both forward and reverse. If I give it enough throttle to go faster it sounds fine, but that's really hard to do when I have a rider in the water and trying to tighten the rope.
The problem is the same in both forward and reverse. If I don't give it enough throttle the engine knocks a little and sounds like its going to stall. If I go back into neutral its fine. I recently had the carb rebuilt and don't think that has anything to do with it. Any ideas??
I did also notice that the rpm's seem to be too low at these speeds, close to 500...
