Ive got my eyes on a motor that makes 51 horsepower for less than $200 its a rd350 and its a twin two stroke. Not positive but a thought. I could use a dually carb banshee throttle set up and premix the gas. They were known for there monster killer abilities back in 1975. It weighs 90lbs all alone ya think this is heavier or lighter? anyone ever heard of the swap?
