[Farmall] Easier to Start?

Here is your problem:
"It also only runs well on half choke, "
You have fuel starvation.  It may be an internal passage in the carburetor, 
or a flow restriction somewhere back through the fuel line to the tank.

Subject: [Farmall] Easier to Start?

Good Evening,

It's been awhile since I have had to bring you an issue on my Farmall
Super A.  It has always been hard to start, taking a long time of
cranking (normally two periods of three seconds each) before it will
begin to fire.  Lately, the electrical system has acted up, and I am
trying to start it with a hand crank.  It's great exercise, but not the
greatest use of my time.  It took a good 20 some turns with the hand
crank to get it to start firing tonight.  I'm surprised my arm can still
type!

Is there any sort of "trick" some of you know of to convince a tractor
to start easier with a hand crank?

In case it is important, the Super A has a good magneto, D21 spark
plugs, and a Zenith carb.  It also only runs well on half choke, and
there are no adjustments on the Zenith beyond the idle mixture.  I know
the impulse coupling works, unless I am mistaken.

Thanks for your help.  I'm sure all of you have had the tractor that
won't start well with a hand crank!

Ben Wagner
