I have searched high and low through posts etc also tried Google and You Tube! I can not get this plug out and the one that came with the used engine I purchased is busted to hell along with a few other plugs. Can anyone tell me the trick? I have been told it has a clip; I see none! I know it has a double o ring as does the solenoid I have the engine hanging all ready to come out but do not really want to cut the harness and splice it especially living in S.E. Michigan. ( Salt city) PLEASE HELP!!! I am at my witts end. Normally I have no trouble finding quick and easy posts and answers to fix what ever but this one escapes me. Thank you all very much for all your posts and valuable information!!
