Hi all,
Completely new to this forum as a registered member. I was hoping I could throw my issue out there and have some eyes on it and get some opinions. I have a 1995 Mercury Force 40HP outboard new to me last year. Marketplace purchase, former owner couldn't get running. Turned out to be a fuel pump issue. Rebuilt fuel pump and stuck new ignition coils and spark plugs on it as the plug wires were damaged, Motor fired right up on starting fluid on the test bench. Stuck it on the pontoon and ran it the rest of last season with no issues. Fogged the motor over the winter storage and ran the carb dry. This year, this motor will not fire up for me whatsoever.
Things that I've done so far include:
New fuel filter
New battery last year, checked and fully charged this year.
Checked for spark and replaced spark plugs. Plugs looked, and look great, nice healthy strong spark.
Compression test about 135-140psi on both cylinders.
Timing seems to be within spec, checked with timing light. Haven't touched the timing since owning this motor.
Kill switches are functioning properly
Air and fuel delivery seem to be just fine.
Opened, checked, and cleaned carb. No dirt or debris, no stuck float.
I cannot for the life of me figure out what I'm missing here. This year, it won't even sputter on starting fluid. When I attempt to start it with the fuel line attached and choked, fuel and oil will dump out of the exhaust and just the wispiness of exhaust smoke, so something seems to be igniting. No fuel coming out of the exhaust when not choked. I figured I flooded it when I first attempted to start it, but I've cranked it as close to WOT I could have gone with no plugs to get the excess fuel out and left it vented overnight. I'm going on nearly 2 weeks of off and on working on this thing and basically made no progress. I've pretty much given up and now turning to the web for help lol. Any insight would be greatly appreciated!
