The maximum RPM rating for this engine is 3600. This means you could run the engine at that speed and also means the engine should never exceed this RPM speed.

Staff Answer
This engine could be used in a snow blower, providing that the shaft dimensions, overall dimensions and mounting base are similar to the engine that it is replacing. We do not offer a kit that would convert this engine to electric start, however we do offer a similar engine ( item # 6013) that comes from the factory with electric start. See link below for more details.
