I am pretty green with ohv engines so I thought it would best I asked you folks your opinion. My engine keeps killing spark plugs. They are not carbon fouled or oil fouled as far as I can see. They just stop working. I am at a loss as to why it?s happening. If I pull the plug wire and wedge it 1/8 inch off the top of the plug, it starts up and runs fine. If I connect it to the plug then it won?t run.

It has:

New plugs
New coil
New ignition
New carburetor
Fresh gas
Charged batter

Has anyone ever experienced this? What could it be???
