xlhbob,

The 45 sounds similar to the 33cc one. I went through the same procedures to convert it. I couldn't use the prop driver from the 25cc homie weedeater engine because it slides over the crankshaft and is tightened down with the prop nut. The 33cc needed a prop driver with a threaded hole to screw down onto the flywheel. It just so happens the prop driver from my failed Ryobi conversion fit perfectly. Might work on the 45cc too.
