Hi All,
Need some help with a diagnosis. Have a 15 HP Evinrude 1986. First noticed issue on the water, motor seemed to be starving for fuel in high idle (would run about 20-30 seconds and die) but ran fine in low idle. Brought the boat in and let it sit for about 3-4 weeks, now won't start at all.
Confirmed both spark plugs are good. Each cylinder is getting about 60 psi of compression from 3 good pulls (pullstart).
Carb has been thoroughly cleaned with cleaner and compressed air. Gasket and float both are good.
Drained old fuel and mixed new - fuel pump appears to be working (squirts when pulling cord while disconnected from carb).
Carb bowl is filling, jet appears to be clear from obstructions. When attempting to start you can hear initial combustion and a few rotations but quickly dies out. If I let it sit for more than 5 minutes it takes a little longer to sputter out (3-5 seconds).
My guess is that fuel isn't making it to the engine but I'm not sure what to do next. Would appreciate any and all suggestions
