Thanks for the help
Hey Grant this is Alan, we raced in open nitro at Wynnum couple of weeks ago.

My advice with the piston is to very carefully clean it with something like autosol making sure that you only clean the top surface of the piston. Do not touch the sides at all. Sometimes the burning and pitting is only due to excess oil sitting and burning on top of the piston. When you clean it it should be flat and shiny. Try that one first.

What type of motor is it?
