Hi guys. Haven't been on here in a while and I'm a little stumped. I've got a 1970 kohler 400 two stroke and when I'm standing beside the Argo with one hand on the key and the other on the throttle, I feel a little shock while the starter is engaged. If I hop into the argo to start it, no shock. I'm assuming because the tires are insulating me from ground. I'm not positive but I have a suspicion that when that fault occurs, it only runs on one cylinder. Any ideas where to start??
