Yes I have read about the burnishing tool and that’s what I will use. I have a new bushing, new bronze gear and am awaiting a new shaft. I plan to check the distributor shaft length as I now really suspect it is too long and that may have caused the quick wear.
I see there is at least one person that’s using an iron gear on a billet cam. I was hoping to hear from more folks that have done this, the iron has higher carbon in it and likely would wear out the cam gear. Nice to prove this one way or the other.
Meanwhile if anyone has a melonized gear they want to sell, let me know!
