I had Dad's Wizard Powermatic 12 and hunted with it for years. Didn't have a squeeze bulb; the gas tank had a button you pressed with two fingers to prime the thing. Pump it until you smell and see gas running out of it and it started right up. I had one of those cold hearted winches but mine had a primer bulb. It was a '57 model I believe. As I understand, they were made by Mercury and were comparable to their 15 horse model. More than one cold morning, I would have to take the motor off the boat and set it in the front seat of my car to warm it before it would start. The last year I had it, to keep it running, you'd have to keep squeezing the bulb or the dang thing would die. Many a pucker factor dark thirty river runs.
