[AT] Easier to Start?

Oh and while you are at it take the fuel line off and blow carb cleaner 
through it (assuming it still has the factor metal fuel lines on it) and 
blow compressed air through it and repeat until you're sure there is no 
trash, rust, scale or gunk in it.  Check your sediment bowl strainer and 
make sure it is right and clean.  If someone has put an inline fuel filter 
on it take it off that might well be part or all of your problem.  Most of 
the inline fuel filters you see are designed for a pressurized system and 
don't gravity flow enough fuel to feed the carb on an updraft system.

Subject: [AT] 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
