[AT] back to business

[Spencer Yost]

Magneto work is one of my favorites.   Carburetor work is my least 
favorite.  I worked on a DLTX John Deere B carb  on and off for week 
because it wouldn't idle but would stay running throttled up.  I worked 
on this until I realized it has a small crack in the casting where the 
idle circuit passed close to the outside.  That hairline crack kept it 
from idling.    Brazed it up and at least it idles now.   But sheer luck 
allowed me to see it.  No amount of effort and smarts can overcome 
"invisible" .   It just isn't like a magneto where you can rule out 
components and test as long as you understand the principles.  Carbs 
seem like black magic.   You do all the rights things and they still can 
make a fool out of you.

The rotator cuff surgery really put me behind so Lord knows when I'll 
get around to working on tractors.  My wife has a an old Mercedes and 
her transmission is next on my list and the tranny is on the bench.   It 
just needed a new clutch but I am resealing the tranny while I am at it 
.  As for tractors and engines I am looking for an engine show in the 
next few months because it seems like shows are the only time I get to 
work on either!

And Charlie - thanks for the video.   Being able to so closely integrate 
and use multimedia like this video clip is one of great benefits of the 
forums.


PS:  Still testing and tweaking security settings.    So the services on 
the server will come on line and offline from time to time for very 
short periods of time while I test.  Just a heads up.

Case used a heavy felt seal to keep the impulse clean. While this might be a good idea on a working tractor, tractors that get abandoned outside for 40 years are a different matter. This thing managed to keep so much moisture in the impulse housing that one of the pawls locked up and the seal itself is severely deteriorated. I never could get the back half of the impulse off (you need a special puller) but I was able to free up the pawl. Now I've got to attempt to straighten up the threads on the shaft so I can get the nut back on. Replaced the primary wire and cleaned up several corroded connections and decided to give it a test. Without the cap on it I'm getting over 5/16 spark on impulse. As soon as the owner brings me the cap I'll give it a few minutes on the mag tester and make sure everything e!
