let me start off by saying i dont ask for help unless im pulling my hair out. this ignition system is so simple its crazy, and i cant get it to run. its a 2 stroke lawn mower engine in the water. im losing sleep over this thing. 1955 evinrude fleetwin 7.5 7518. no spark if spark tester is connected to the plug in block. if i run a wire from a head bolt to the tester(light bulb kind) it sparks like crazy. i swear i could spin the flywheel by hand and it would spark that way. cant get it to jump a gap with a plug or a gap tester(its old and rusty, wired wheeled it the best i could) at all. with it all wired correctly, i get a hit on a cylinder every once in a while. ran before i replaced a bunch of stuff, just not well. had a low speed dead miss, had one original coil in it and original wires that were green at the coils. replaced points, condensers, coils twice, wires twice, plugs(i got it with rj12c's in it, put those back in) and rebuilt the carb(not that matters). got aftermarket coils first, they wouldnt go in far enough and hit the flywheel. bought oe coils. bought a cheap set of automotive wires with the oe coils. for a 3.8 chrysler i think. couldnt get any spark. it dawned on me that theres quite a bit of resistance in those automotive wires after it wouldnt spark with oe coils. ordered sierras copper core wire kit and ends. copper core in there now. the plugs arent internally broke. point gap is a tight .020. i have good grounds everywhere. practically no resistance, .1 ohm. coils are flush with the plate boss like they say they should be. flywheel magnet seems strong. im ordering oe j6c plugs hoping the resistor might be screwing with me. it ran before so i hardly doubt thats it. couldnt find coil resistance specs anywhere but theyre brandy new. its almost like the brand new coils are weak. it sparked once or twice with the automotive wires, did i possibly burn up the coils dumping the voltage into a wall of resistance? thinking about throwing the old coils in to see what happens but i got alot of work. annnny help is greatly appreciated!
