I544 carburator no gas

I544

New User
I have a I544 with I think the C200 engine. I have the gas tank that is above the starter. My gas goes from the tank to the sediment bowl to the other side of the tractor to a mechanical fuel pump. From the fuel pump it goes to the otherside (right side) to the carburator.

I have removed the line from the sediment bowl and got fuel flow. I then went to the inlet side of the fuel pump and got fuel flow. I then went to the outlet side of the fuel pump and had no fuel flow. I then motored the engine and still had no flow from the fuel pump.

I removed the pump and pushed on the cam arm of the pump and it pumped fuel. I then replaced it and motored the engine and it still did not pump.

So I am wondering what is going on??? I did read that the I544 was a gravity flow system. Is that correct or does anyone have an idea of where I should go next.

Is there a possibility that my cam is bad that is suppose to operate my fuel pump and how would I check that.

Mine isn"t.

I suppose that"s possible but it"s more likely that the pump is defective in some way. I had a run of problems with pumps (that worked) leaking fuel into the crankcase. I installed an electric one. It"s worked fine for about five years now.

No manufacturer name. Model number is 60106 and I got it at NAPA. It"s rated 12V 4-7PSI. I screwed it to the base of one of the broken pumps and installed the resulting assembly where the old pump had been (seal the hole with a gasket).
