Honda GX120 4HP with a non-keyed shaft- suggestions?

[cmmatthews]

I have a really nice (starts on the first pull) Honda GX 120 4HP motor to put on the Carter Kart I am restoring for my son. The shaft appears to be a 3/4", but it is not keyed and is threaded on the end. It was originally on some type of water pump. Are there any clutches available that do not require a keyed shaft or should I try to get creative with the dremel and cut my own keyway?

This is my 3rd diy keyway from an idea by Mr. Kibble.

You cut that pretty good Mr. Russ!

Thanx. Takes much time/patience.
If you look carefully, you can see where original clutch slipped (end of youtube vid) before keyway was cut.

Think I will cut it...

After seeing everyone else's results, think I will cut my own keyway......think this motor is strong enough to propel a manco dingo? I may just use this one since the shaft size is the same as the stock B&S 5 hp.....then I could just use the stock torque converter

Thanks everyone for the help!

No not enough, you want at least 5hp, AND MUST use the torque converter.

Yeah I can see the rotational scuffing.

I have a video I am making about how I go about making a keyway in a keyway-less shaft. I haven't worked on it in a while though. When it's all done, I'll post it up.
