1942 Dodge 1/2 ton "Job Rated" pickup carburetor

[Tubeviper]

Ever since I got my pickup, I have noticed black water coming out of the tailpipe, black spark plugs, etc. So it burns too rich... But then I found that the high-speed mixture is not adjustable. Finally I looked and saw its got an E9G1 carburetor which is for a larger engine.

 

This engine should have a DTC1 carburetor, right?

 

Thanks!

What are you using for an air filter and is the engine timing set correctly?

It has the standard oil bath air cleaner and the timing is set correctly. But I need to check and make sure that the 73 year old harmonic balancer hasn't shifted...

Is a DTC1 carburetor correct for the '42 Dodge 318 in a 1/2 ton pickup?

 

Thanks,

Assuming you typo'd 318 for 218 then yes.

Yes, typoed .... I meant 218.... OK I'll find a DTC1. That will probably stop my plugs and tail pipe from getting blacker than they already are.

 

Thanks!

Check the heat range on your plugs too. Someone might have changed to plugs to help accommodate the larger carb.

Look up a carb chart. There are other #s with the same specs. I think DTE1 and DTE2 are the pilot house carbs and they should work for you too

[Tubeviper]

Well I am not having very good luck locating a DTC1 and am thinking that I should look for a different carb. The previous note stated DTE1 and DTE2 carbs would be a good bet. Which carb would be the best match for the DTC1?

From what I saw both the 3 of those have the same specs.

[Tubeviper]

As noted above, my current carburetor is an E9G1 which was intended for 2.5 to 4 ton trucks I believe. No wonder the engine is running so rich.

 

Now theoretically the only difference between what I have and what I need is the jet and metering rod size. But I have been told that the Carter B&B jets and metering rods are not interchangeable.

 

But I was wondering if anyone could tell me of I could take my current E9G1 and by any means convert it to a functional equivalent of a DTC1/DTE1/DTE2?

 

Thanks!

[Tubeviper]

How do the E7T2 specs compere with those of the DTC1/DTE1/DTE2?

 

Thanks!

[Tubeviper]

No more imagining and deciding which carburetor to get - I found a DTC1!

 

   

[Tubeviper]

I got my DTC1 carburetor all rebuilt and stuck on the manifold to find out that the idle mixture screw does not work.

 

The engine will run on partial choke but not on open choke. Must have blockage or some major vacuum leak somewhere.

 

Questions:

 

1) Does the Idle Mixture Screw regulate fuel or air?

2) Where is the problem most likely to be?

 

Thanks!

It regulates the amount of fuel in the idle mixture. Did your kit come with a replacement for this? Some do ....some don't. Makes a big difference to how well it runs.

Also have you tried putting a vacuum gauge on this engine to see what might be going on? This simple tool can be quite enlightening.......

No screw was supplied in the rebuild kit but I have a parts carburetor.

 

If one removes the idle mixture screw with a full floatbowl, should fuel come out or not?

[Jeff Balazs]

I believe you can get one seperately from Mikes Carb Repair or Roberts. They are easily damaged so your old ones may not work correctly. Do not tighten them with a screw driver. You should be able to change this out with the engine off without fuel pouring out.

I think it regulates the AIR.

***Notice:For idling conditions the mixture must be VERY RICH (AIR-FUEL ratio about 10:1) or 10 pounds of AIR for each pound of gasoline,as the speed of the engine increases the mixture should become LESS rich until at about 20MPH the mixture should be 16:1.This is the ratio which will give BEST ECONOMY and should be maintained until a speed of 50MPH is attained.As the speed is increased ABOVE 50MPH the mixture should become richer until at top speed the AIR-FUEL ratio should be about 13:1.(TM-9-1826A ORDNANCE MAINTENANCE,CARBURETORS CARTER).

Thanks!

My engine is a 251 cubic inch displacement,25"(Bore=3 7/16" and Stroke=4 1/4").The correct carburetor are E7T1 and E7T2.For B2-H,HA,HH,HHA,B3-F,FA,G,GA,H,HA,HH,HHA.
