Hi, WillJB.<br /><br />Your carb isn't putting fuel into the airstream.<br /><br />It could be the outlet from the tank. There is a screen there that may be clogged. The valve at the outlet might be clogged, the line from there to the carb, or the carb may be clogged.<br /><br />I would remove the valve assembly from the tank, drain and clean the tank and the line to the carb. If that doesn't reveal the trouble I would overhaul the carb.<br /><br />I don't find a J-10 in my model listing (goes from 1922 through 1964). The JW series of 3 hp engines were made from 1952 (JW-10) to the late 60s.<br /><br />Recheck the model number, and let us know what you find.<br /><br />Good luck. :)
