[AT] John Deere H

[Bill Brueck]

Tyler, I had the same situation with my 39 H.  I used it on a buzz saw for
several seasons before I restored it.  Always started hard, a little
gasoline or ether into the intake screen was real helpful.

When restoring it I found that the choke plate has a spring-loaded trap door
in it, this engineering marvel is to keep the tractor from flooding itself
when it starts and you still have the choke on.  Spring had broken on the
trap door thus I wasn't getting a good choke.

It was a great starting tractor after I replaced that spring.  First
compression after a good suck for fuel and it took off every time.  But
lately it has returned to the old habits.  Haven't taken the carb off yet
but I bet the spring I fit into there didn't hold up.

Hi all,
My grandfather owns a John Deere H, it's a 39 I think.
It is all original, the mag might have been redone at some point, he doesn't
know.
It runs excellent for a hand crank original JD H, but here is the issue.
Every time you hand crank it, you have to give it a shot of starting fluid
in the intake.
I went out to his place this weekend and drove it around for awhile on
Saturday. Went back out to his shed yesterday, gave it a wirl and wore
myself out cranking. Of course this was with no starting fluid, because he
and I both know that on a Gasoline engine, eventually you will bend a valve
in it.
He said the mag probobly needs taken apart and polished up.
Any other ideas as to why this could be?
Is it just that the mag is about dead?
Thanks for any help!
Take Care,
Tyler J
