No pictures but when I was a junior in high school(late 60s) a senior brought a cart with a 650 BSA to auto shop to work on. It was said he never got it out of 2nd gear. Phil
Kid up the street from me growing up had one with a 305 Honda on his . His Dad owned “ The Wonder Worker “ 66 SS Plymouth .
Anyone know what brand this one is? Originally had scrub brakes. The double tube and narrow steering hoop should be good clues
Mine isn't exactly a go-cart but it is built with some go cart parts.... 1x3 - 1/16th wall tubing frame, Honda 90 wheels, 6.5 hp Predator engine. Steering components and drive are all go cart stuff.
