Is the $30 cost of a new crank gear and the upgrade to the aluminum gear worth the risk of future failure? My customers and I say no. If you are throwing a motor together to go to the auction, I will send you a box of used timing gears that I usually throw away, cause they aren't worth the risk to me.

My thoughts exactly. I went one step further and got the bronze matched set from Dan.
