So a buddy asked me to get his fathers old snow thrower going the other day. It was bought by him in '73 and my friend has had it for about 10 years and has never started it. I pulled the carb off cleaned it, cleaned the plug, checked for spark....... WTF no spark...... Dammit. So much for this being an easy fix. Take the pull start off and the flywheel. Points look brand new, test for continuity is good. Clean the points, magnets and contacts, cross fingers, put flywheel back on hit starter button, we have spark! Put it all back together, add gas and it starts first touch of the button, NICE.
