Welcome to the forum.
Here's a post where someone used a rag joint on a 32 spoke - see Hoze513 response:
Reading a couple of other threads, it wasn't recommended since the wheel isn't as strong as a 36 spoke wheel.
I would recommend forum member AI.Fisherman's doc on setting up your engine: https://docs.google.com/document/d/1...QUZq2qXXE/edit
Become familiar with engine as much as you can, so that when problems occur, you'll know the engine inside and out.
Don't ride that engine flat out or it is going to wear out very quickly.
