How to fix fouled plugs
So anytime you flood your engine, people automatically say "replace plugs". I fouled out some brand new BR8EQ14's while burning off all the assembly lube in my newly rebuilt motor, and got stranded on campus. Since I was in the auto lab, I grabbed a Mapp gas torch from the tool crib and a wire brush. My plugs were covered in a black, tar-like substance, so I tossed them into a bench vice and hit them with the Mapp gas torch. All of the contaminants burnt off and left me with a grey ash, which I brushed away with the wire brush. Put them back in and the motor started instantly.
Cliff Notes: Don't replace your fouled plugs, hit them with Mapp gas and a wire brush to restore them to like-new condition.

This sounds interesting but, I'll add my method as well,
1)soak plugs in carb cleaner/chem dip over night
2)use med. bristle brush to clean electrodes and ground straps
3) wipe plugs down and allow to dry for about an hour
4)reinstall plugs and take her for a drive
This works great if you got a spare set of plugs and allows for an otherwise
good set of plugs to stay out of the trash can.

Good tip. I've always been able to hit them with a wire brush and get 'em shiny as new so I guess I haven't fouled plugs badly enough to need the torch on them. I do torch them whenever I flood it, if only to burn the gas off.
Despite that, I used to be quite the nut for replacing mine every other season, so I've got two or three sets laying around that I've wirebrushed and keep around for troubleshooting purposes.

Get a spark plug cleaner ![bgth](https://www.rx7club.com/images/smilies/biggthumpup.gif)
I think Harbor freight sells them. You just put some sand in the little bag they come with and pop it on the air compressor... Stick the plug down in the hole and press the button. WOALA BRAND NEW PLUG!!!
I ride two smoky street bikes... Can ya tell??? LOL

After seeing this thread I tried the mapp gas technique on my fouled up chain saw plug, and now it runs like a raped ape! I'll add this to the yearly ritual for all my lawn stuff.
