I've got a Dolmar 460 that the owner says isn't running right and I can't get it to start at all other than priming it. I've had the carb off the saw but doubt that's the problem. This saw also has all the stuff off the clutch side and there's no visible seal around the crank except there appears to be one inside turned around backward because I can see the spring. When I pull the starter the crank turns but so does the seal next to it! I think I need some professional help..
