Weedwhacker Engine Project

[sanddrag]

I've had this little 18cc weedwhacker engine for a while now (runs beautifully by the way) and I can't figure out how to start it. I have already machined a mount and shaft for it. See, the pull starter is on the front of the engine, not the back, so I had to remove the pull starter to mount the engine because the only bolt locations are on the front (actually, they are the ones the pull starter housing mounts to.) So anyhow, now I've got this nice little engine on a nice little mount with a standard 3/4" keyed shaft and no way to start it. No, I did not think this project through, LOL Anyhow, I was thinking to use a 3/4" clutch bearing on the end of the output shaft, and then make an adapter shaft that fits this bearing into a standard 1/2" chuck drill. Will that work to start the engine? McMaster says the bearing can take 16 ft-lbs of torque, is that enough?

I know a chainsaw engine would be much better but its the fact that I've already got this one and I don't have a chainsaw one that makes me want to pursue success with this one.
