I can't say it for sure, but the carb on my '54 that I cooked and rebuilt three years ago, ran briefly, and then parked is not passing the fuel like it should. I've got gas at the carb connection, but only what is poured down the throat will briefly run the motor. I did put fuel conditioner with the fresh gas, but should I look for something stronger, or fire the cooker up again? What product would work the best to clear out stale gas?
