What is the felt gasket for?

That goes on the choke rod just underneath the top. The types that need this will have a clip under the top to hold this in place.

Springs for the choke pull-down

These are not available, however we do have two possible replacements, these were recommended by another rebuilder. We haven't tried them ourselves.

No Fuel Out Venturi

My Motorcraft 2100 serial D2PF GB for a 1964 1/2 mustang 260 does not send gas from the venturi into the 2 barrel. When the venturi screw is removed there is gas when the accelerator pump is manually pumped. Also when screw is loose there is gas. Engine fires with starting fluid every time. I can't understand why it doesn't flow. Help! I love your helpful videos but I haven't found anything about this. Seems like some sort of adjustment.

• Venturi passages are plugged
• There should be a check ball and a check weight in the main discharge hole. The hollow screw goes over the check weight. If for some reason the screw is holding down the check weight (maybe too long), it would cut off the fuel.
