When installing spark plugs, they won't stay put.
The ignition coil is good. what is the tool that keeps the spark plugs in place.

Hi,

Are you screwing them into the cylinder head and then tightening them with a spark plug socket? Also, what do you mean by they won't stay put? I'm confused on that one.

Take a look through this link and let me know if it helps. Also, let me know if there was any trouble removing the old ones. These engines are known for having spark plug threading issues.

Take care,
