from my Dad on how to clean blackened spark plugs

" In a small glass bowl of water and efferdent (or equivalent) overnight
Came out pristine. "

Love that tip! Whoda thunk?

Thats a slow way a much faster one is to just heat the end with a propane torch turns back to white in a few seconds.

And for those of us without a propane torch, just lean out the mixture until it stumbles and hit the highway hard, same thing.


I also swap plugs at cleaning time, any rich or slightly oiled plug goes into a cleaner plug's spot.

whats wrong with slow ? does everything have to be instant drive-thru ??


besides if are sleeping, no precious time wasted with propane torches..

It's kinda nice putting in fresh new plugs once in a while. They're not THAT expensive.

Except I ruined a head trying to get one out recently. I like shiny new plugs. They seem to make it instantly run better...but I know its prolly in my tiny mind.

My bus has had the same plugs in it since I built the engine. About 14K miles so far. Fouling plugs are not a sign of good things. They mean bad out of tune carb and or wore out engine, which a out of tune carb can cause in short order.
