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!

Been a while. And a year since I finally fixed it for good!
All that poking around...
Rebuild Carb, Intake Gaskets, Fuel Pump, Fuel Lines, Etc.
The ignition started eating up Modules.
And I mean quickly.
Got me to thinking...so I saved up some pennys and bought another HEI.
Dropped it in and VaRoom!
Been running great ever since.
No stutter, no sputter, and just running way better than ever.
Old HEI was the eBay thing suggested here.
New one is cheapest MSD from Summit.
I now know there are two levels of Chinese parts.
Thanks again for all the help.
Cheers!
