Differential trouble

[gray horse]

I've had the cart out and it was running good but seemed slow for what is in it. Yesterday I decided to tear into it and see if I could find anything wrong. I discoverd that the flywheel had moved, probably during assembly, and was not advanced as it should be. Fixed that, no problem. I then looked at the clutch and noticed that the inner oil seal on the secondary had come out. Pulled the clutch and found that the inner bushing is shot, it's missing 2 plastic ramps and the 2 seals are gone. It appears as though there is a taper iin the middle of the input shaft. Will measure this today. I assume that this is not normal and that the shaft should be flat and straight across. Am I right in my thinking? Will let you know what I find.
