Carburator on a WD

I had the old 48' WD running like a top and then the carb went south. I got a rebuild kit and tried to rebuild the old Marvel Schabel but I rung one of the brass set-screws off down in the bottom of the bowl, so I called this site and ordered another carb. They sent me a Zenith carb with a lot of instructions on how to adapt it to work on the Allis. They told me the Marvel was no longer available and they were substituting the Zenith on the WD. My old girl has not run right since then. I have no power and I am fouling plugs left and right. I have adjusted everything I can including the jets on the carb, the timing, plug gap, etc. Does anyone know where I can get another Marvel-Schabel carb for the 48' model WD, or do you know someone who can tap out the brass set screw and rebuild it? This old tractor ran like a top before the old carb went south! Thanks for any help.

Thanks for the great info folks. I did check to see that I got the right carb and I adjusted the carb according to the instructions (1 1/2 turns out on the top adjustment and 2 to 3 turns out on the bottom adjustment). Still sounds like a JD popper. I can't tell you how many times I have changed the pulgs. It runs good for a few minutes and then starts popping again. I an not using oil and I am not getting much smoke until she starts running rough and rich. If it is not the carb, I cannot imagine what else it could be. The only stone left unturned would be the coil. When I changed to the Petronix system I kept the stock 12 volt coil that I bought from the parts store. I will probably run the rebuilders down and see if they will at least take a look at my old carb. I am frustrated.

Bob,
There is one person you might call for info on both your ignition and whether your MS carb can be repaired. He does a lot of work on both for AC owners and I have called on him for advice and bought ignition parts from him.

What Stu said on the Zenith. Do adjustments while the tractor is running at operating temprature. Is the float good? "This old tractor ran like a top before the old carb went south!" Maybe the old carb didn't go south, if a different one is not making it run anybetter.

Before you give up on the Zenith, you might want to check the list in the link and make sure that it is the right one for the '48 WD. I have an original Zenith on a '51 WD and it works fine when clean & adjusted properly.

Sounds like you might be running a little rich. Recommended initial setting for the upper idle adjusting screw is 1 1/2 turns out. Recommended starting point for the lower main jet adjusting screw is 2 to 3 turns out, depending on fuel & atmospheric conditions.

Today's Featured Article - Tractor Traction - by Chris Pratt. Our first bout with traction problems came when cultivatin with our Massey-Harris Pony. Up till then, this tractor had been running a corn grinder and pulling a trailer. It had new unfilled rear tires and no wheel weights. The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc ... [Read Article]
