Cleaning Spark Plugs

How come I've never heard of this before - to clean plugs, just heat them with a propane torch to burn the carbon off.

I imagine this isn't news for many of you, but it was for me.

That will clean SOME spark plugs. If the reason they are fouled is a cracked insulating ceramics then heating them does not help much. You can just use a lighter too. Also some times warming the plug up will help start a flooded engine.
 
My dad used to do that occasionally, he would bring them in and put them on the gas kitchen range. when they got red hot he would take them out and put them back in, and the engine would start. I have done it with good luck with small engines and a propane torch. I try to get the plug back in when it's hot, seems to help.
 
My buddies Ski Doo snowmobiles were hard starting, especially when below 0*. He used to bring the plugs inside and set on the radiator in the motel room at night. Made a world of difference the next morning.
 
BIG difference in a DAMAGED plug and a DIRTY plug.

Damaged plugs you throw away... or core them for adapters..

Dirty plugs you can clean...

I used to frequently clean spark plugs with a propane torch, but these days I never have my propane torch handy when I need it. (It's usually over at some rental property I'm working on.) An acetylene torch with a brazing tip works REALLY good, EXCEPT you have to be very careful to avoid melting the electrode. A gas stove works, too, if you can sneak in the kitchen when momma's not home.
