If the ez-start is turning itself, but the engine is not turning then either something is wrong with the EZ Start gears (not likely) or the One-Way Bearing is slipping on the starter shaft of the engine. The pro .15 I had was notorious for getting cracks in the OWB causing slippage. If its saturated with oil it can slip too. Personally, I'd pull the ezstart off,<span style="font-size: larger;"> clean out the OWB with brake cleaner or carburetor cleaner and put it back in. OWB's should be installed dry - no oil or they can slip. If the starter shaft is extra shiny, I'd get some 800 or 1200grit sandpaper and lightly scuff the surface of the shaft. All you're trying to do is rough up the smooth surface so the OWB has something to grab on to.</span> If none of this works, replace the starter shaft AND OWB at the same time.
Perfect suggestion. Worked like a charm
