i did this back in the day on a lawnmower engine and i just ran the pipe from the supercharger after the carb it worked to pull fuel as i pointed the comp air at the cylinder. unfortunatly we had to run rich untilll the pump made boost enought ot lean it out.. worked well only thin i did wrong was had no relief valve and blew the engine up

gave up on the blower. there is just not enough room for it and still get the body panels on. going with a 40qmb big bore build now. hopes to get it in there with close to stock wheel base so i have a wheelie machine! my gy6 engine is for sale if anyone is interested.
