tryin to break in new engine, ruff idle

If you primed your engine by removing the intermediate shaft, it's real easy to get it off one tooth when you replace it. It will still run and you can get it pretty smooth, but it will back fire and you'll know something is just not right.

Big screw driver and a telescoping pocket type magnet make it easy.

Since then I've marked it with a center punch, so I have more to remember than just a slot, and I put a paint mark inside the engine to line up with it, and I take a picture, just in case something comes up and it takes longer than I thought.
Cause I don't want to do that again.

I had a new carburetor on mine, so I thought for a while that the carb. was the problem.
Just a thought.
