Fouled Plug #1

[MagmaJct]

When you get around to replacing the valve stem seals, which was the source of my number 1 & 2 plugs fouling, get a tool that allows you to pressurize the cylinder to keep the valves from falling in when you remove the keepers.

I found my Sears compression tester hose was a perfect match for my pneumatic quick disconnect. Once I replaced all 16 seals, no more fouling.

Before I made this repair, number 1 was fouling so bad a chunk of carbon was often bridging the spark gap making that cylinder inoperative. Once the bridged carbon was removed, I'd relocate that plug to a different cylinder to "self-clean."

I eventually had to move to a hotter plug, and use a "non-fouler" just to "get-by" until I was eventually able to make the proper repair.

Good Luck!
