Simplicity Snowbuster 724 Snow Blower

Manufactured around 1980, this engine has a 3/4" x 2-5/16" shaft. The H70 engine is no longer made. The newer Overhead valve style engines are about 2" wider than the H70 engine toward the right side as you are facing the crankshaft. You will have to make sure this will not be a problem for you.
