Default Re: Can I use an old lawnmower engine?

Yes- it would have to horizontal shaft
You'd probably want to use a centrifical clutch- and there are a number of issues with chain sizes and gearing-
You'd probably have to have wide cranks or mount the motor high enough to clear the cranks- some people use shorter cranks I think
I had a Briggs and Stratton on a Rupp mini back in the '60's- it was dependable but not all that fast, and with the small wheels

Here are some 4 stroke motors at Harbor Freight

If you want a 4 stroke motor, I think I'd go with a kit myself
