7.5HP 4-Stroke Go Kart Engine OHV Industrial Grade Gasoline Engine 212CC Go Kart Gas Engine Motor Electric Start Go Kart Engine for Compressor Scarifier Lawnmower, Shaft Diameter 78 mm (US Stock)

I should've gotten a refund. This pos didn't run from the start. Also, the stupid clutch drive is some weird size, we tried 3 sizes and none of them fit. Plus it never ran , and for the 10 seconds that it did, it literally sounded like it was gonna explode. Biggest junk I ever bought. I usually have good luck with stuff like this, but not this time, do not buy this, you're throwing your money away if you do. I had to spend a lot more money on something way better, like the predators fromHB., just start from there and save yourself headaches.

After testing several engines for my homemade go-kart, this 7.5HP beast stands out! The electric start is incredibly convenient (no more sore arms from pull cords), and the OHV design runs noticeably smoother than cheaper alternatives. I was skeptical about the 212cc displacement at first, but it delivers surprising torque – climbs hills effortlessly while maintaining fuel efficiency. The 78mm shaft integrated perfectly with my torque converter setup. What really impressed me was the industrial-grade build; after 20+ hours of rough off-road use, it still starts on first try and shows no oil leaks. Perfect for serious hobbyists who want commercial-grade reliability without the price tag!
