Help Needed With Weed Eater Motor

Another Question

I'm also wondering what gear on bicycle I should use to pedal assist my friction drive set-up?
 
That will probably depend upon how many gears you have. I would recommend trial and error as the best means for making this determination.
 
edger parts

to lift your engine off your tire: go to a lawn motor repair facility...ask them for the part that the edger uses to lower the blade...attaches to the motor and it is held in place by a system of holes on a plate. Should be very cheap and very "adaptable" for your purpose. Attached find very "crude" drawing. Good Luck!!

Hello from Washington State;
I was a motored rider for awhile, until i went to a local discount store, where i chained my bike to a lite post, only to find it gone when i came out about 30 minutes later.

It was an 80 cc motor mounted on a mountain bike, it really was nice for about 2 weeks:(
 
motor pivot

Hi,
FWIW, I just built a friction drive, rack mount for my mountain bike.
I bolted the engine to a piece of 1/2" plywood and then bolted the plywood to a strap of steel used to hold a 4x4 post for fencing.
The steel had a threaded hole and a long, lag bolt. I found that the bolt fit nicely in 1/2" aluminum tube. I brazed the tube to an aluminum strap which I then bolted to my frame.
At that point, the bolt goes through the tube and the engine pivots around the bolt. I just put a handle on the other end and you can pivot the engine on and off the tire as needed.
I hope this helps.
Here's pictures.

Whipper snippers older than about 8 years dont have clutches, new ones have centrifugal clutchs. I have one 30cc without and one 31cc with.
