2000 125h.p. starting problem

[wally]

I JUST TRADED FOR A 2000 125 H.P. MERC. IT IS HARD TO START FOR ME...I'VE USED THE FUEL ENHANCEER JUST ABOUT EVERY WAY I CAN THINK OF TO NO AVAIL; ALSO, TRIED USEING THE THROTLE. THE BULB IS NEW, AS ARE THE PLUGS. ANYONE HAVE A CLUE AS TO HOW TO GET THIS THING STARTED?

I trim motor down all the way, pump the primer bulb till firm, give a little throttle,push in key to choke and hold for a few seconds then start engine. If fails to start right away reprime primer bulb and rechoke.
