norman,

Read the thread on weekwacker engines. I'm thinking to just leave it engages most of the time. I might put a cable on the choke and just ride it turned on and turned off. And yeah I hope it has bearing or at least bushings on both sides. Those things are pretty light and I think I'm going to go with a spring without too much tension at first.

My electric bike rollers were like an inch or 1 1/4 pvc joints which would be a quarter inch larger in diameter. The work pretty well and since they are smooth I think they have less wear on the tire. However if they won't pull my fat butt up a small hill, then I go for the rasp kind and let the chips and rubber fly lol...

Actually I was well satisfied with the electric power just the lack of range made me nuts.

And yes I need a welder even though My next door neighbor has one. I will bolt everything up and slide down to his place and con him into welding it for me. I got the 20" wheel on the project bike. So I'm just waiting for the engine.
