Hello all-I bought a '62 28 horse johnson and have come to the conclusion that I'm fixing everything but it's real problem and I need suggestions.I bought this a couple months ago not running and have done a carb kit,cleaned and gapped points,synched the carb and advance plate,checked fuel flow out of pump and for air leaks,etc-it seems everything I do finally has it running decent but quickly back to the troubleshooting agian.initally,the carb was flooding so I did the kit and got it running but it was suffering from a bad lean sneeze.I went back through the carb,re packed and set the needles and this time learned about welch plugs and found some old packing or something under there-I found the throttle wasent closing and synching the linkage had the motor sounding pretty good.got on the lake and it ran OK although flat after about half throttle-I shut it off and then it wouldnt start. here at home I got it kind of running but it kept sneezing/dying and finally wouldnt start. top plug looks good,bottom plug black and sooty.I am missing something for sure-if the motor was dropping a cyl because of a coil or condensor,wouldnt it still fire on one cyl? I am used to other types of engines were the throttle operated the carb and the timing advanced from weights-this is a whole new animal for me and I could use some help!
