what do you guys think this plug looks like?? do i need to go to a colder one
What kinda lawn mower have you got? I swap mine with the Z turn from time to time to let the plug rest. It works.
How does it run more impotently? If I remember right you have an 18 KTM? Same bike and skill level as I am, different fuel. This is my plug on C12 and rejetted that runs like a raped ape.
I've since switched to U4.4 and rejetted for that and it runs even better. Your plug looks like its a little rich on the low end. When you rev off idle does it hesitate or rev right up? Pull hard out of corners?
