NOPE!
Let it get up to operating temp. Shut it off then try taking them off. Just watch where you put your hand or you will end up with one hell of a burn.

 

You pull a spark plug wire while the engine is running, you will find out real quick just how powerful your ignition system is.

 

I feel this is appropriate to go with your reply lol.

 

If the wrong plug was put in, the threads may be extended into the chamber too far and clogged with carbon.

Try tightening sightly, then back it out. It will only move a little, but working it back and forth each time breaks the carbon off. It should eventually come out.

Forcing it too much will ruin the threads.

 

I wish this forum had a "like" button! Ha!

 

Did you get it out?
