So your tractor won't run at all? Do you have the OEM Marvel/Schebler TSX-692 carb? Is the OEM Fuel Shut-Off Valve intact or has it been replaced? Do you open the valve when starting and running? I would be willing to look at your carb for you but suspect it isn't your problem. Rebuilding all the major components on a Ford are highly recommended before even considering buying anything made 'new' today. If you carb passes the fuel flow test, chances are the root cause lies elsewhere, i.e. electrical. Many suspected fuel issues turn out to be electrical and vice versa. If glass bulb drains and engine stops running, you are not allowing fuel to get to carb so valve is closed or plugged.
