I've just been going through ideas I had after looking at a few old weedeaters, of course these engines are very small I wouldn't go under 25cc and pedalling would be neccesary. If you could attach a pulley to the shaft while still keeping the pull start then you could build a mount for the engine to stay in place and have a heavy spring belt tensioner to act like a clutch that uses the same clutch lever for the 2 stroke kits. Or maybe do the same thing for the regular 2 stroke kit engines, release the clutch while pedaling. The only problem with these old engines is the carburetors they have diaphragms that go bad constantly. I have an old 25cc homelite trimmer that I know runs and an old ryobi 31cc trimmer that might need a new coil. You would have to put a sheave on the wheel for the belt. Maybe you could even make a 2wd with friction drive on the front and belt drive on the rear! ha the only thing is you'd have to use a more powerful engine on one of the wheels atleast I think that's what someone said. Or use an electric hub wheel on the front and have the small 2 stroke setup on the rear. They make a dual cable brake lever you could use to attach the 2 throttle cables together if it was 2 engines.
