1988 force 50 hp, ran for two hours fine, idle and wide open. Stopped to fish, would only idle on warm up. needed to keep pushing the choke to idle. Quits when put in gear. primer bulb is soft. Did the same thing a day before, but could get in gear by using the choke. Very cold blooded, hard to keep running, when first starting. Seems to be out of gas changed tanks, same problem. New gas in both tanks.
