the push button is black. it has a kill switch with a lanyard and a stop button on the end of the handle. I started it up the other day, ran around the lake and slowed down to adjust idle. got it set the best I could and went back to the dock. shut it off and it wouldn't restart, no spark. the next day I pulled the carb and inspected it. looked good and reinstalled. she started right up and ran great. shut her off. later that day went to start it...no spark. how do I bypass the kill/stop switches? just disconnect them?
