I don't like the starter springs. After a lot of use they create noticeable wear on the carb body and aluminum piece in front it.

The little starter I posted above is pretty high RPM - a lot more than a standard starter - without enough torque to turn over a locked up .020. I always prime then turn an engine over 2 or 3 times by hand before staring, regardless of the engine size or whether I am hand starting or using a starter.
