[AT] John Deere Carb.

[Louis Spiegelberg]

I use the brazing tip on my torch.  Adjust to low heat.  Heat all the brass
screws till you see a green flame.  Remove heat as soon as the green flame.
Let the screws cool, and then they should turn out very easily.  Once you
get the screws out heat the stem red hot.  Let it cool.  Use the appropriate
size tap and make some threads in the bottom side of the nozzle.  I use a
long screw to fit the threads.  I put a nut and a few washers on the screw.
Thread the screw into the nozzle, then tighten the nut down on the washers
(the washers should be resting on the stem). The nozzle should come out
then.

I finally went ahead and took off the carburetor of my John Deere AR. Fuel
starvation was causing it to run only on choke. On dis-assembly I was amazed
at how dirty it was inside that big cast iron carburetor. Looks like mostly
gum and varnish from stale gas. Its a fairly simple looking carb but I am
having problems unscrewing the two big brass screws that hold the float
pivot pin in place. I don't want to damage the heads or twist them off but
so far they have resisted my efforts to loosen them. This is the DTLX
(Marvel Schebler I think) carb and the first of this kind that I have ever
worked on.
