My 1982 70 hp. Merc won't start until I prime the carbs.if I restart immediately sometimes it'll fire up.it runs well once it's started.I throttle it up and choke it but no luck getting it started.I've check and fixed any air leaks between tank and carbs.I've disassembled fuel pump and all looks fine.The bowls on both carbs are filling up prior to starting.primer bulb gets hard and seems ok.haven't had it on the water yet just trying to get it running right.once I prime carbs it fires right up and stays running.Idles fine and throttles up ok Just won't start till primed.thanks for any help .
