Hi guys,

I have a non-keyed crankshaft on my clone engine I've been planning on using on my go kart build, and need a keyway to use the old manco torque converter that I have off a tecumseh ohh50. I just wanted to check in to see if there are any special considerations that I need to make when grinding in a keyway, such as why there is a taper on the end of the crankshaft of the tecumseh and if I need to replicate that, also if it matters exactly where I make the keyway on the crankshaft, in relation to the the position of the piston, ie top dead center piston, and top of the shaft.

Thank you

or you could get a new crank. but you could probably get by with an angle grinder and a dremel tool. roughly cut the key way with the grinder and finish with the dremel.
