RE: Lets do a 40cc ryobi conversion!
ok...today I removed the coil and the muffler. The block is now ready for some milling! I cant believe how light the coil and flywheel are.The flywheel is also pretty thin too.Its a bummer there mounted on the side like that. The crankcase is small, as you can see. That should make the engine really want to draw fuel/air.
After the milling is done Ill start the prop hub.Im thinking about a 18-6 for a starter prop...hows that sound?
