I had to fix the recoil on my 20 HP 1983??? johnson seahorse, minor repair, loose retaining bolt. I decised to check my plugs, as I had not done that since I got it last May. I pulled out the top plug and find that whoever had installed it crossthreaded it when installing it. The recieving thread is essentially gone. Is there a way to fix this? I was careful to collect all shavings before I turned it over to blow out the cylinder.
Needless to say I am less than pleased. The people that I bought it from will be getting a request to look into the matter. However the motor was quite inexpensive, and really had no warrantee.
Thanks for your help.
