Carb. freeze up?

I have a Case 530 gas tractor that I rebuilt 3 years ago. I ran it this past weekend raking hay and it started misfiring like it was running out of gas, so I cleaned out the settlement bowl thinking that would fix the problem, but it didn't help. My dad thought that the carb might be freezing up. I never heard of this before, but sure enough, the top of the carb was as cold as ice. It ran this winter and the past two summers just fine. Is this just an adjustment issue or is there something else wrong with the carb?

I'm no expert here by any means, but I had a similar situation with an old forklift once (can't remember what make or year it was actually, just remember the situation). My solution was to run a piece of copper tubing off the cooling system and wrap it around the intake just below the carb. The heat from the coolant was enough to keep it from frosting. Solved my problem. Never know, might work.

Better check the intake manifold to see if it is sucking in air. I've even heard that adjusting the valves may help (doesn't make much sense I know). If none of these work, try making a heat deflector out of a piece of aluminum flashing and attach it to the side of the riser pipe opposite the engine. Curve it so heat from the block is directed on the riser pipe.

I don't have a fix, but I have seen the condition. I have an LA gasoline manifold on my L, and sometimes when running at fast idle with no load, the outside of the carb gets wet with condensation. When weather conditions are right, it actually builds up an exterior coating of frost just below where it bolts to the manifold. I suppose it's a combination of venturi effect and the evaporation of fuel that cools it so. I've never had any operational problems from it, though.

Is your intake manifold warping away from the head? We had a DC that was doing the same thing & we fought it for a long time. We thought that dirt in the fuel system was the problem. While taking the carb off to clean it for the umteenth time, we discovered that manifold bolts were just a little loose & manifold was warping away when it got hot. A new gasket, new bolts & filing the manifold flat solved the problem. (My $0.02 worth. jal-SD)

SCs are prone to that. Is your engine running up to proper temperature (around 180 degrees)? Getting the manifold warm from the engine heat usually cures it. The cause is the gas cools the metal where the air intake flows into the manifold. The venturi effect of the moving air makes the problem worse. I can usually nurse my tractor through this by adjusting the choke until the engine gets all the way up to temp.

It is running right at 160-180 degrees. It seems to get worse the longer it runs. Thanks for the advice.

I have a Case 200 that I have had since 1966. I've had the same problem with it since I bought it. It occurs during hot weather when the humidity is low. It doesn't appear to freeze up, it will start running lean. It will start leaning out, and the longer it runs the worse it gets. Finally I will have the choke completly pulled out to get it to run. The amount of load the tractor is under doesn't seem to have any effect on the problem. Numerous carb cleanings and rebuilds, along with several condenser and coil replacements have not changed it in any way.
