SUPER H WONT RUN

You're not getting fuel to the engine. You need to disconnect the gas line at the carburetor and see if there's a full stream of gas from the tank. Hold a clean container to catch the gas.
If there's just a trickle of gas you may have blockage in the tank, sediment bowl or gas line.

If you have a full stream of gas to the carb remove the tube fitting where your gas line connects and look for a screen. It may be plugged with rust and dirt.

If there's no blockage here your carburetor may be gummed up from the old gas. Probably needs to be thoroughly cleaned in carb cleaner. The jets may be plugged.

Do you have good suction when holding your hand over the throat of the carb? Hal

Take the fuel line fitting out of the carb. Many IH carb. fuel line fittings had a screen made on to the fitting. I worked on what I remember as a 424. The owner said it would run for a while then slowly run out of power. This tractor had a fuel pump that had been changed a few time that seamed to fix the problem. I tried a tune-up and was about to send the tractor home. I noticed a small fuel leak at the place where the fuel line fitting screwed into the carb. I decided to remove the fitting and add some Teflon tape to seal the fitting. This is when I found the screen, that was almost completely plugged with straw particles. This plugged screen was the tractors problem. I just lucked into this fix. IH is the only tractor I have seen use this. CHECK YOURS.

Check in the fuel tank---Sometimes the sediment assembly has a brass sreen on top of the inlet assembly. Also check for anyother stuff in the tank sometimes plastic can get filleted off of a gas can spout and block the flow. It appears to flow fine under no load-but draws it over the tankoutlet under load..just my experience..gobble
 
Danny, there are several things that can go wrong inside of that carburetor. That double float can out of shape just a little bit and then it will hang up on the sides of the fuel bowl and won"t drop down to allow fuel in. If that tractor has just sat for awhile, the gas in the carb may have become sticky and caused the float valve to stick shut, or, there is gunk down in the bottom of the carb which has plugged up the main metering stem. All of these things will require the carb to be removed and taken apart.

I"m not all that far from you if you need help.

There are a lot of folks who "rebuild" a carburetor by just replacing the old parts with new, and then wonder why the thing still won't run.
 
When I was a teen my dad had a 1939 Ford he bought new just before the war. It started to need a new fuel pump quite often. I watched the mechanic change it and when it did it again I replaced the pump. It didn't last too long either. One of my classmates worked in his dad's shop and his dad was a machinist and a mechanic and I told his dad about the fuel pumps failing. He said there's something else causing your problem and told me to pull the push rod. He said either the cam lobe is worn or the pushrod. He brazed the end of the puhrod and told me to try that. Never had anymore fuel pump failures. Hal
