Thread: SBC 350 - Only certain cylinders are firing. HELP!

An old trick we used to do to clear fouled plugs was to put the plug wire on them loosely so the spark had to jump a little to the plug before lighting the plug off. Theory was that it made the plug run hotter and cleaned it up, don't know, but had success with the method a couple of times way back when I was a young man, if the plug wasn't too fouled.

Doesn't cost anything to try it and only takes a two or three minutes to see wether it is going to work or not. Course back then, we used to lightly sprinkle borax down the carb to re-seat the rings on a worn motor too. I'm not recommending that though. LOL!

Don't know about borax, but have used feldspar and limestone (Bon-Ami cleaner) to seat rings.
