I had the same problem one & learned the hard way. I had the wrong coil ! Get the right one & replace condenser & points & youll be fine! You can get them to run on the others but points don’t last long & your engine will run hot! Hold your coil wire about an inch away from your spark plug itl Start & run, that’s a definite sign it’s too hot a coil !
