Ok,
I ordered and installed the driver portion of the comet 20. We now need to align it. The original motor mount holes leave the driven about .5" out of alignment. I THINK. I was told that I needed to align the Centerlines of each pulley. The problem is that since the comet 20 has the driver and driven facing each other, and it seems that the driver shrinks and the driven expands, I dont' know where the centerline I should be measuring off of, is. Any tricks like measure X" from the back of the pulley or anything like that. Also, It would help if I could relocate the driven about .5" outboard with the use of some washer type shims between the shaft shoulder and the pulley. How far can I push the cast iron spline sleeve off of the engine shaft and still be safe. I don't mean manufacturer's suggested spacing. I mean real world for a kids kart, what's the smallest amount of bite could I use. 1/4 the length, 1/2 the length?
I will also try to post pics later.
