Default How to align motor on kart frame

I have been fixing up my grandson's go kart, and when it came to putting the motor back on the frame, I'm not sure how to make sure the motor is properly aligned.

It's a dead axle kart, and the rear sprocket is attached to the wheel hub. I used a dial indicator mounted on the frame to get the sprocket spinning true with no run-out.

When I put the motor on, it looked crooked. There are angles in the frame tubing which makes is hard to get a reference point. I put a long bolt in the crank to try to visually align it with the axle. But then, it is not aligned with the motor mount plate.

After putting the chain on and spinning the wheel by hand, it seemed a lot smoother if I clocked the motor all the way counter-clockwise (standing behind the kart). The chain made less noise and seemed to turn smoother.

I used a straight edge against the wheel sprocket to the clutch sprocket to make sure they were inline with each other.

Took it for a test ride and it seemed to run ok, the chain stayed on, but want to make sure it's reliable and SAFE before I put my grandsons on it.

Any good ways to verify the engine is mounted correctly?

Do you have a straight edge at your disposal? I'd line up the sprockets with it and see if the alignment is off.

Just from the pics you posted I would say it looks pretty good. If you aren't hearing any binding or other noises coming from it when the wheel is turning, you should be good to go. You can test by using a straight edge like a long ruler or something against the sprockets

yes, as mentioned in the 5th paragraph, I used a straight edge on the sprockets.

Then I think you are good to go if there are no obvious problems

Slowpoker (but I hardly know her ) that looks pretty aligned to me. I think the process you did goes above and beyond what most folks do on yard karts The wheel/sprocket are not going anywhere, so the engine is your only adjustment.
