I bought this 38cc 4 stroke bike berry engine kit with the friction drive for my bike but I want it on my go kart. My only concern is the sprocket connection to the engine this engine. I do not have one yet. There is a rubber cylinder to connect them I think but I never received it in package and I don't know what size? The engine does not look standard for the flywheel/clutch thing I know it is a 5/8" clutch I was wondering how I could attach a clutch it to the existing screws? I have a sense for it but I am open to all ideas and comments.
