Ok friends.... My neighbor is wanting to get into racing carts and asked me tonight if I could build an alcohol engine. I told him Im sure I could if I could just figure out the little specs. Does it require special valves, head, piston, rod, crank, cam etc? I read this post about modding a Briggs engine http://www.oldminibikes.com/forum/b...some-guide-modding-briggs-5-hp-flatheads.html but it dont say if this mod will work for a alcohol setup? Any advise on this would be greatly appreciated.
