7.5HP 4 Stroke Gas Engine, 212CC Engine Go Kart Engine Mini Bike Engine, Horizontal Shaft Gas Powered Engine Pull Start Air Cooling, 14.25in x12.32in x12.99in

Be warned! This engine has a 20mm shaft, it's NOT a 3/4" shaft. They didn't list the size and I assumed it was going to be a 3/4 and but it's not. Since I didn't ask first I'll leave it with a neutral rating but it's also so cheap it's not worth sending back. Looks like I have my work cut out for me.

Don't buy. The output shaft was almost 1/16 larger than the claimed 3/4". Took 3 hrs with belt sander to sand the shaft down to the right dimension so the 3/4" clutch could fit on. Got that sorted, mounted the motor filled with oil and gas and the thing won't run for more than 30 seconds at a time. It's not getting gas. Now I have to pull the carb and find the restriction. I'm a machinist, fabricator, with a lot of experience working with engines. These problems are well beyond the average persons ability to correct. Don't buy this cheap engine. You will regret it. I am displeased with Amazon for selling cheap out of spec. nonfunctional Chinese junk.

Great engine, I installed it in my kart. These engines seem to be built pretty well, one pull and it starts it up and it's the perfect engine for me.

The engine was easy to replace, all the bolts matched without any problems. It started on the first pull and worked great. All in all, this engine is a great value for the price and quality 👍

Engine was easy to replace, all bolts matched with no problems. Very, very happy with this engine. First pull of the cord engine starts immediately and runs well. This engine is a great value for the price and quality 👍
