I inherited a late 80's model Honda 2.2 4 stroke outboard about three years ago. I had the local Honda dealer tune it up and replace the carbuerator and it ran great all summer. Unfortunately it was in storage for the next two years without having the gas drained from it. Upon trying to start it recently, it would run for up to 5 seconds if I put gasoline directly into the air intake, but that's it. The spark is gapped to 0.022 and it's firing. I dismantled the carb and it looks good. It simply behaves as if it is unable to pull the air/gas mixture from the carb into the cylinder. There is only one needle valve that I can see and it looks clean. The carb float looks good and does not appear to be hanging up. Any suggestions would be appreciated.
