Got my replacement engine (thanks Jeremy/birddog). Got it all put together and things went pretty smooth. I'm being very careful to run at partial throttle, especially for the first 100 or so miles, and I'm experiencing a surge that makes me nervous about a problem and also makes the ride less than enjoyable. I am being subtly pitched forward and backward as I go down the road. It is not smooth. It's unsettling.
If I am at any partial throttle level, the net effect is that (like I already said), the power is surging - so 1 or 2 seconds of smooth power, followed by a fall-off in power, followed immediately by another 1,2 or 3 seconds of smooth power.
I don't think the first engine did this.
It's not the engager, it is definitely staying engaged. I have it permanently engaged and there is no disengagement going on.
I'm thinking (based on reading threads here):
oil sensor switch?
the large amount of grease I packed in the gearbox this time, affecting the clutch?
kill switch wiring, as Irish John mentioned in a thread?
the engine not firing on a cycle(s), for reasons other than kill switch or oil sensor?
fuel flow?
Now, as another clue, keep in mind this is ONLY during partial throttle. I tried running wide open for a short stretch and the ride becomes smooth, no surging.
Thanks in advance...
