My output shaft, that the wheel should attatch too is far too long. The threads aren't long enough in the first place to tightnen the rear wheel on, but it's about an inch and a half too long. This is on a new engine I've just bought online from scrappy dog.
Any ideas? I have two other engines for parts, so I'll take one out of one of them, but I'm sure it's not going to be the most enjoyable to have to do.

I have a 49cc 139QMB, that I rode home (Almost) but it died on the way back. I pushed it home, because it wouldn't start and stay running. The next day I tried to ride it to school, and it started up and after about 20 minuits of riding it it would die when stopped. It would start, idle, then with open throttle... Only go 5mph under its own power. It didn't sound like the engine was revving near max. To get it to go full speed and get full power from the engine, I had to push it until it was going around 5+ mph, then it would take off and die again once it was stopped. Now, after riding it like that for a while it quit starting so I...
So far I've: Replaced the CVT belt and adjusted the valves to .004.
I took it for another test run, rode for about 15 minuits, and ended up pushing it back about a mile and a half.
Could this maybe be the CDI box or something? The carburator has clean gas it (Opened the drain valve and ran fresh gas) and the throttle body moves in accordence with the throttle.
Thanks for your time and any help in advance
