i think they are talking about the fuel pump, never heard it called a pulse valve, but it makes sense. can you squeeze the bulb till it gets hard and it doesn't go down? Pull the fuel pump off the block and see if it has fuel coming out of the port

I have heard of the check valve for the air side of an optimax be called a pulse valve. Not anything called that on a carbed merc. Sounds like you might need to clean the carbs and change the plugs.
