M-37 carburator

[newbee101]

OMG what have i done??? I have just removed the carburator and found that it is a Ball and Ball????? Made for Chysler Corp the only number is on the intake tube 1268923-1 in searching there are only two carbutors ever mentioned as being used in this vehicle and this is not one of them does anyone have any ideas???

The standard M37 carb is a ETW1. I'm assuming the Ball & Ball you have is likely from a civilian spec engine, we see this change out frequently. You can simply find a good core ETW1 and either build it yourself or have it rebuilt to the original specs.

We offer rebuild service if you need it.

If youve got the E7T2 civvy carb its an easy rebuild yourself. I sourced my kit from the local NAPA that had it on the shelf for 18 bucks. They run great on the civilian carb although its not the correct carb.

So back to carbs... Is the civilian model a better carb ?

Only if it works and the military carb doesn't.

For what the truck was designed to do, the military carb would be the better choice. You wouldn't be able to ford any streams with the civvy carb.

Thanks Lifer, But my trucks days of going deep fording are over
Besides out here water is pretty rare we cross riverbeds not rivers !!
I just thought the civvy carb might be easier to work on or maybe help get better milage.

The answer to both those questions is no, in fact when it comes to rebuilding, I'd rather have the ETW1 any day. Fuel mileage is what it is, carb won't matter. The only thing that will possibly help the mileage to any degree is drastic measures such as higher gear ratios and over drives. Even that is questionable and depends on the terrain and traffic condtions in which you are operating. If conditions are so that these measures can be taken while allowing the engine to relax a bit, mileage will improve; but if you are in conditions where the over drive will just create more load on the engine without allowing it to relax, you won't see much if any difference in fuel economy. It is still a great upgrade because of less wear and tear on the overall drive train however.
