Wow, does that thing ever bring back some memories. We used to mess with the engine a bit back then, would go a heck of a lot faster than 40....but not with me on it. Don't recall how we did it but we used to somehow shim the centrifugal clutch so it would grab quicker. First time I tried it the sucker flipped over on top of me it grabbed so fast, just a hair above idle. Have to chuckle at the signage on the back fender....."your next." Begs the question....."my next what?" Probably meant "you're next"...must have skipped class in third grade.
