Troy-Bilt 4 cycle weedeater motor on 26 inch Schwinn, Built 2 cycle 80cc, vibrated like crap, removed it and added HS142 and runs smooth. Then built a 79cc preddy on Huffy. Got bored and decided to try friction drive, mounted ok, but still need work and engine runs good. Rode it about 1 mile and decided I need to finish setup. Kill switch, throttle etc.

I am trying to figure out how to make a handle to raise the little engine off the tire when I come to a stop or back home. If you don't pick it up, it will eat a hole in your tire! also engine runs like a bat out of torment amd idles good, But it is very hard to crank, I use a drill driver to crank it but it aint easy, even with a new carburetor.

Bldr1000- maybe the tension is too loose on the tire?

Neither of my friction drives suffer from that problem, and I have no lift clutches attached. My motors stop spinning when the bikes come to a complete stop. I'm using BMX pegs for drive rollers, so that may have something to do with it. Still using the same stock tires for both of them, with very little wear for the mileage.
