Inherited my late fathers 123, which he became second owner of in 1974. She had a been sitting a few years after we bought a snowblower. Got it running last November, had a head gasket blow upon start up, battled a bad ignition switch both have been replaced. Had it running so so, could never get the aftermarket carbs to adjust right, gas pours out of them. My problem now is back to where I was last year when I first attempted to get it running. I get 12v to the coil nothing on - on coil till I rotate and get the points opened, I then have spark and the test light comes on. I get spark when I turn the key off when the points are not opened, Engine wont even crank, brand new battery. I get nothing on the test light when its in the coil secondary. I'm thinking bad coil or bad condensor.
