So this motor was my grandpas and growing up it seemed to me like it ran no matter what after being in storage for 8 years or so not properly stored a cousin took it home to get it running for dad ( the cousin is a marine mechanic in Osage beach) two years later we get it back and we really don't know what all he did to but it runs and spits water out we never had it the water for proboly four more years all this time I would hook up the ear muffs once in a while and start it. This year I have had it out more than a hand full of times and seams to just not rap out or want to idle I found some gunk in the fuel screen and running 93 octane supposedly without any ethanol in it. I changed the plugs last fall but I just went to orielys and they cross referenced them and after reading other post I wonder if the plugs are not burning hot enough, sorry for the book but there is the background
