10-20 carb adjustment??

U.P. john · Jul 10, 2010

I've been working on a 1927 mccormick deering 10-20. It does run, but very rough. Does anyone know how to adjust the carb? its a solid brass one, or know the valve cleanence? I'm sure it won't run as smooth as a farmall H, but I'm hoping with a little tinkering it will smooth out some.

I figured it out. There are two holes on top of the head. They are supposed to be priming tubes. I plugged the holes and she smoothed right out. It was drawing too much air and running lean. Now to find the original tubes to put in holes.....

I believe that is 1/8 pipe. Fordson House also has the primer cups. You might find some at a swap meet if you really look.
