Guys, by the time you have a suitable intake manifold and prop adapter machined, make provisions for CDI ignition and adjustable timing, engineer and make a mounting setup, and buy a carb, muffler and ignition, you will have some bucks invested in the engine, and it still is a Chinese engine. I have Kawasaki and Echo engines in that size range I can convert for you. They are better engines, with known reliability and great power, and are easier by far to mount. The price for them completely rebuilt, converted, and test run would be close to what you would have invested in the engine we are talking about, but it would be genuine Japanese high quality. I know that "first rattle out of the box" the engine and its price look attractive, but when you look at the big picture, things change.

If anyone does one of these, please remember to make whatever carb mounting you come up with completely isolate the carb so it can't heat soak. I ran into that problem. Trying to tune a carb that is too hot will drive you nuts and you could even ruin the engine with a lean run. Hot restarts will be a problem as well...
