So I have 4 motors, a brand new rs8 w/back plate, rs5 back w/plate and a xtm that’s having issues with the pull start. Its been one thing after another. I was going to buy the nova .28 today but I feel like that’s a waste of money. Any advice or even point me in the right direction would be greatly appreciated thx
Your Mach 427 is going to share parts with other engines/brands. There are only so many actual manufacturers. My advice would be to try to get to the bottom of what other engines' head buttons are the same unit and get one of those buttons. The next advice would be to try a Helicoil repair, if the size is available.
