Good morning! Haven't been doing any fishing, seems like I have been spending every weekend in the shed with the motor on the stand. Anyway, I had the compression tester on last night and when I took it off the bottom cylinder, the spark plug thread repair came out with it! I was wondering what you guys thought. Should I have another thread repair put in or should I just go ahead and put a new head on it. It's a 1977 25hp Rude. I have a used head, head gasket, and new thermostat in my ebay shopping cart for $106, shipping included. Should I buy the parts or should I have the threads repaired again? Also, does anyone know a good independent mechanic that would make the repair if I went this route? Thank you for the help!

P.S. If anyone is looking for something to talk about on this cold day, I have a few other repair questions on this motor too!
