its vacuum pump runs off cam

Oh... my mistake! Sorry you’re having so many troubles with your machine!

So seeing as you have had the fuel pump apart, I dawned on me this morning(pun intended), though I could not think of it at first.
Again seeing as you have had the fuel pump apart, look at the second picture at 4:02 on the second page and the problem probably looks you in the face. Now look at the instructions underneath and be sure the head is in the correct direction.

Should be problem solved, after all this. Do not do anything but unhook the lines and remove the 4 head screws, if it is wrong spin it 180 degrees and put back together.

i installed as it came apart the inlet with 90* on it goes to carb right?

[curtisbyrne]

and thats the direction of the arrows

Is it possible to test the fuel pump on the bench? Hook up to a battery with a line in a jar of gas (make sure you don't make a spark!) and see if the pump works. My guess it's the fuel pump.

Hey Curtis, Is it possible to do pretty much what Mowbiz says . Just pump the lever by hand?

[ARGOJIM]

That's possible, but if the checkvalve is on the wrong side, nothing will happen. If tne arm is not on the lobe nothing will happen.

[ARGOJIM]

When pump is installed you should feel suction on the side.

I learned something today...I never knew about mechanical fuel pumps! What part on an Argo spins the cam to make the pump work? Internal to the motor or otherwise? I understand the talk about “the cam” now. Does the pump arm need to be lubed?

[curtisbyrne]

the lever is constantly lubed yes the crank makes the cam go. by hand?? i would imagine the cam spins pretty fast......if i spin the top 180 the flow will be backward according to the arrows.

[curtisbyrne]

give me a link to an electric pump so i can buy one im through with this hard starting no fuel device

[curtisbyrne]

[curtisbyrne]
