mach .28 L8T
I can't figure out why I constantly blow plugs. After one run the plug fails. I tried the MC59 plug, the McCoy plug and the stock plug all of them blow after one run. Does anybody know what may have happen to my engine ?

I had it happen with a sportwerkss v2 that I had sit for a couple days after putting lot of after run oil in . . . I went through 4 plugs that day then let sit for a week and it never blew another plug . . . it didnt blow plugs just needed different plug to start . . . those plugs were still good . . . are the plugs no good after one use ?

RE: mach .28 L8T
Yea the plugs are bad, they will not light. But I found the problem.........a piece of thread from the button head got into the cylinder and made some raised marks on the head and the top of the piston. The cylinder walls were not damaged at all so I think I can still run without a problem. I sanded the raised marks on the button head and cleaned out the threads for the glow plug. I will post results ASAP.
