I bought this to fit into an electric crawler. I ran 3 tanks of fuel through it while on a test stand and was surprised at how well it ran. Unfortunately the first time I started it after installing the new flywheel and clutch bell the crankshaft snapped between the clutch and flywheel.
I bought one to do a off road truck build for my youtube channel, total scale detail easy starting stable idle the best of the best with this engine, they also have clutch flywheels and 2 speed clutch bells. if you want to see how good it fits and runs check out the link https://youtu.be/heFrmAABWEU
bought this engine and i think the starter kit but no instructions on how to to assemble i wouldnt have the slightest clue on how it works
