Here are 3 options for you at this point:
1. Bring the head into an automotive machine shop for them to repair it;
2. Repair the stripped hole in the head with an insert
3. Buy a new head, rebuild the engine from the head gasket up.
Take it to a shop. Cheap fix or call and ask if they have a deep socket!
Screw out spark plug then screw in non fouler then screw in spark plug in non fouler.
If the spark plug is stripped, replace it, if the hole in the cylinder head is stripped, the first thing to do is run a tap or thread chaser through the hole, if that does not work, you will need a helicoil http://en.wikipedia.org/wiki/Helicoil
Could be that the threads are stripped on the plug or the head where the plug is screwed in. Or maybe it's the wrong plug..
If your spark plug doesn't screw in your threads might be messed up. Run down to your local Part store and ask for a Thread Chasser($arround 10$) and screw that in to your spark plug housing just as you where screwing in a spark plug. What this does is it replaces the threads. Take out the chasser, Lubricate your spark plug and you should be good to go.
Not tightened properly? Threades stripped?
No.
You might try to use krol as this oil can creep into the smallest cracks to help loosen the spark plug. http://www.kanolabs.com/ The next problem will be the threads probably will be stripped. Use a Time-Sert insert to repair the stripped threads. http://www.timesert.com/html/sparkplug.html http://www.timesert.com Good luck!
yes but is is cost effective? that's your call
If the actual threaded part in the head is stripped, you have to use a tap and re-thread it. to avoid metal in the cylinder bore, u should take the head apart from the block to do it. I recommend doing this yourself, as a shop will probably charge you over $1000
On a carburetors motor pull the coil wire from the distributor cap (the plug wire in the center of the distributor). This is usually found between the air cleaner and the firewall. Remove the desired spark plug from the engine block, plug it into the coil wire and touch the spark plug body (the metal portion) to the engine block while cranking the engine. You will see spark if the plug is good.
you get a spark plug socket or one of similar size to fit the spark plugs, then you just put it in the correct location and screw it in snuggly(not too tight cause you will break the ceramic casing), then connect all the spark plug wires
