Picked up a Masport 460 but it's not one I'm used to. There's no throttle or primer that I can see on it. There's a dial that regardless of where you turn it, still produces spark. I got it started by putting petrol in the spark plug hole, it then kept running as there was some petrol in the tank. Turned it off by pulling the spark plug cover off. Possibly there's a part or two missing, anyone help? [Linked Image]
