Hello, I have a Fordson New Major Gas tractor that will run too lean with no choke. I checked for air leaks using starting fluid, propane and carburetor cleaner and could not find any. I have boiled the carburetor and sprayed every passage out with carb clean and compressed air. My main issue is that the manual says to remove the metering jet I need a special tool, and I cannot get to the main jet without removing the metering nozzle first. This is a fixed jet carburetor so I can't adjust it at all.
I also confirmed that I have good fuel flow from the pump to the carb.
