Hello, I have an 89 125 A, it's on a 20' maxum. Ran it all week on our camping trip with no problems. Acted like it ran out of fuel today, refilled, started fine, then stalled, wouldn't start again! When I pump the bulb it gets hard(fuel comes out of bottom carb bowl) I have spark at all four plugs, fuel pump looks good. Don't know where to go from here? Any help would be great, Thanks much, Tim
