to mount on motohuffys sister. have the plate in place already.
(http://i519.photobucket.com/albums/u360/gstwin/Mobile%20Uploads/downsized_0803021646.jpg) awaiting hte studs for the 66cc engine to arrive. which will go on the other frame, anyhoo looking for a SMALL 4stroke engine. or any engine wiht a flat bottom mounting plate built in, which can attach to this plate in picture. cheaper the better in my case. dont care if its chinese even lol
Look into the Harbor Freight 80cc... although I'm not sure it's still an 80cc after the new Predator line. Either way, it's the smallest they have. I had the older model on a motorized bike and it worked well.
predator 99cc aka 3.5hp or 2.5 either way it COULD work. but its a tad pricy. ordered the pole mount for my 66cc enginewhich will mount ot engine, then mount to that plate. so can change engiens with minimal fuss
