Found an older B&S flathead crank in excellent condition. It has a 3/16" (.187) wide key versus the newer cranks with 1/8" woodruff keys. Does anyone make a press fit crank gear with a 3/16" wide keyway or a 1/8" wide key that will fit that crank. I will be using this in a stock block flathead modified and do not want any play between the crankshaft and gear. Thanx in advance for any help.
