Model 25R77S. Ran fine before hurricane Rita and has not been started since (approx. 5 weeks). Went to add fuel stabilizer for the winter and it wouldn't start. External fuel pathway is fine. Bottom half of fuel pump wet, upper half dry. Fuel obviously not getting to carb. Sprayed fuel mixture into carb and will run for approx 2 seconds, until carb empty. Fuel not getting past fuel pump??? Or is there something else that may cause the fuel not to reach carb? Anything else I need to check before jumping to fuel pump replacement. As always, all suggestions appreciated.

Assuming the engine has not been underwater, the carburetor float needle valve is stuck shut and/or the carburetor is fouled. At any rate, remove the carburetor and clean it to cure that problem.
