hello, i have a really freaky situation and i figured id present it to a boaters forum.. first off... i grew up in the automotive world so two stroke motors kinda boggle my mind, my nitro style rc car stumps me as well.... that being said... this problem seems to get me wierd looks from all my car buddies because they are equally stumped... my parents have a johnson sea horse 9.9 on their pontoon boat with an electric start. my dad thinks its a 1985 but we arent sure.. last weekend it was running perfectly fine he says and then all of a sudden it stopped running on him. i went down there this weekend to see what i can come up with.. you know checking wires and spark plugs.. making sure its all good and making good connections etc. well i get the cover off , try to start it a few times and wont start so i pull the top spark plug to check if its getting good spark and the engine fires up and runs fine on the bottom cylinder only while the top plugs out... when i put that plug back in and remove the bottom one to see if it works vice versa, nothing. wont start at all. wont run with both plugs in, or with the bottom one out... only when the top plug's out..... it completely has me stumped and i cant really get to the muskie from the dock! :facepalm:
thanx guys
