Re: New to this: Need advice
Check out the "surpluscenter.com" site. They have some 4-stroke engines available and the Harbor Freight company has 196cc 4-stroke engines for $180.00 Good buys and well worth the investment. I am at 5'10" and 265lbs.
I run the fattest knobby tires on my 26" Murry mountain bike, which is a rigid frame too, and will be installing a Tecumseh on this build. I don't mind spending a few hundred bucks on an engine to haul my lard around. 8-)
