I used the wrong size compression tester fitting and cross threaded the top cylinder hole. Now the spark plug will go in halfway and then it stops. I’m too afraid to take the powerhead off and take it to a machine shop because most of the bolts are rusted and I don’t want to break them. Would a rethreader be my best option? Thanks in advance for any help.
