when most weedeater engines in USA are taken apart to just their engine without the driveshaft extension and the bottom end that does all of the work, most of the 30 to 33cc Two cycle engines ive seen has the pull starter on the right hand side if you was to turn the engine so the output or the crank rotation is facing on the left side as a horizontal shaft engine like that of a Briggs & Stratton horizonal shaft motor for a go-cart or a mini-bike, I have seen some weedeater or small engine leaf-blowers to where the pullstart would be on the LEFT hand side, so the output crank would be facing on the RIGHT SIDE, which is ideal for replacing a bicycle crank with an engine since the bike sprocket is on the right hand side, so you're going to need an engine to where the output crank is facing to the right side instead of to the left,I have bought a 80cc GasBike motor on Ebay for like $100, but the sprocket kit for the rear wheel to be mounted on the left side of the rim is such a pain in the butt to bolt on correctly, if the sprocket rag joint install isnt done correctly to where the bike's factory coaster brake can still be used after mounting the Gas-Bike's rear sproket on the left hand side of the rim, that lopsided install wont line up with the chain and even without the Gas-Bike's engine chain being used, that improper sprocket install will chew up your bicycle rear axle bearings,which brings this small engine topic back to what 30-33cc or even a very small 4 cycle engine leafblower will have the output crank facing the right side,so the pullstarter is on the leftside, and the engine running crank's rotation is still clockwise, but will be on the right side instead of the left side.
