Default Spark plug

I have had luck in the past using air intake cleaner. The spray for cleaning the throttle plates on a late model car. Spray lots on the base of the spark plug and it may work into the threads. Also spray lots down the carb with the engine running to help clean the carbon on the inside. I have found that it is usually carbon build up in the threads that causes the problem of stuck plugs. If the spark plug starts to move, try not to force, spray more intake cleaner around the plug and keep working the plug back and forth a few times. Hope this helps.

Default Spark Plug

If you brake the spark plug, you can fix it with tread replacement, the HELI-Coil compagny makes replacement.
If the spark plug is taper that is an other game, you will need special tool but it could be fix by a machine shop.
If you cannot find the replacement tread if needed please let me know and I will help you.

Default stuck plug

before you resort to brute force there is a product on the market which freezes the item stuck and at the same time lets in penetrative oil when the item compresses....keep applying same until it gives....sorry cant remember the name but read about it in Classic Car magazine......cheers malcolm

Default penetrant

I think this is what Malcolm is referring to, Rost Off Ice from Wurth.
