Paul:

If he found some passages that were plugged, there probably is at least
one
that is still plugged. Boiling the carburetor typically will not get
these
cleaned out. The right sized drill in all passages is required. Some are
hidden. Sometimes with the lack of the correct drill sizes and lengths
running wire through all the passages may get the crud to loosen up. But
the
passage size must be restored to original. I guess there is a better
than
90% chance there is at least one passage still plugged. Compressed air
probably won't get it either.

Do you have a good exploded drawing of the innards of the carburetor and
where all the passages run?  There may be one or more that is adequately
hidden that is being missed. Since this has been this way for a long
time it
may be really corroded and stuck.  I have overhauled many JD carburetors
successfully and the symptoms you describe are almost always (90% or
more) a
plugged passage somewhere. 

Roberts Carburetor Repair in Spencer, IA sells a couple videos, repair
parts
and repair tools such as the correct sized long drill bits for JD
Carburetor
repair. These may be of value. They cover the hidden passages in the
video. 

http://www.robertscarbrepair.com/

I recommend them highly. They are a professional shop, I have visited
twice,
and unlike most other carburetor repair shops, they test the carburetor
for
proper performance on a live engine to ensure "to specification"
operation
before they send it back. Unfortunately, they are so highly respected
within
the JD community that their backlog is huge and repair lead times are
way
out there. The video's may lead you to the plugged passage. Even a phone
call to Robert Beaver might cause him to point you in the right
direction.
He is most helpful on the phone. 

PS: I would not recommend any carburetor repair shop that does not test
the
carburetor on a live engine prior to sending it back. I have no
connection
to Roberts at all. Just a very satisfied customer. If you could find a
known
good carburetor to temporarily try would probably be well worth the
effort.

Howdy
I had the carb 'boiled' by a fellow who does this for extra cash, he
said some of the airway were plugged, but he fixed that (supposedly) ..
the gas runs out almost 1/2 inch past the end of the line, indicating to
me no restriction from tank or sediment bowl, does this sound right, I
mean it runs a good healthy stream.

Paul,
   Try adjusting the main jet all the way in and all the way out if you
have 
little or no change then the main jet is plugged.  It real hard to get
these 
things clean even with today's cleaners.
I had the same problem on one of my tractors it had to run on half choke
but 
after a good working in the fields it seems to run OK now. Just lucky on

that one I guess.
I would take the crab apart and use a blow gun with good pressure and
blow 
out every thing.
