Fiddled with it but the spark plug was rusted on and when I tried to remove it, it snapped off leaving part of it still attached to the spark plug hole. Couldn't get it to turn over mind you I didn't put any petrol in, just wanted to see if there was some movement. Petrol tank clean as a whistle. I don't know enough about these mowers but I understand it's collectible, I don't know how much they're worth but I'd like to trade it for a couple of powertorque chassis, is that fair?
