Q: Have a stuck spark plug and cannot get it out.

Hello. Typically if there is a lot of debris in that spark plug hole then that needs to be removed first. I usually fill part of the hole with either a penetrating liquid or a degreaser. Once that is allowed to penetrate I use a long probe to scrape out all that I can and then I vacuum out any debris. Once that is removed the spark plug can be slowly removed. This engine has a history of these issues and some of the time the cylinder head will need to be removed in order to get the spark plug out.

Hi there. Get some brake cleaner and spray it into the spark plug hole around the spark plug allow the cleaner to help break up the gunk. Then use a pick to chip out the gunk to get a socket on the spark plug. Then you can remove the spark plug.
