Got a 2001 Merc 75 4-stroke carbeurated motor. Left fuel in it for several months, but with Stabil in it. Started the motor (had to use starting fluid) and let it run for 2 hours. Took it out on the water and it died. Could not get it started to save my life. Back at the dock, I replaced the fuel filter, spark plugs, anti-siphon valve and squeeze bulb. Old fuel in the tank had run down to about two gallons, so I added five gallons fresh fuel, some fuel stabilizer and let is sit overnight. Still won't start without starting fluid. Got it running once for about 30 seconds and it sounded like it choked out. Now it only fires with starting fluid and won't keep running. I live on the lake and I can't even get it running so I can get it to a ramp to take it to a mechanic, otherwise I would have already. Any ideas?

Thanks
