Re: evinrude 4 hp worktwin fuel problem
You're describing the classic symptom of a blocked carb. Spraying and soaking the internal passages with carb cleaner, followed with compressed air is the fix. Replace all seals to include the low speed needle packing, gaskets and float needle. All these parts are included in a carb rebuild kit. To check for fuel delivery from fuel pump, disconnect fuel line at carb, coming from the fuel pump. Place this fuel line in a can and pull starter rope. You should see fuel being pumped into the can. When you squeeze the primer bulb, you should see fuel being pumped through the fuel line too. It's the fuel pump that pulls fuel from the tank, not the carb itself. Needless to say, never run the motor out of water. Run in a test tank with enough water to fully cover the lower unit and high enough to cover the water pump. When running, water will spritz from the little holes on the rear of the midsection, you won't see a steady stream of water, just the misting....
