[AT] Carb problems

[Larry Goss]

Right on, John.  There are third party suppliers known to collectors that still have the consumable parts of those engines available.  BUT, it sounds to me like the carburetor is pretty much "wasted" on this tractor.  I would be tempted to hit the flea markets at next year's tractor shows.

Haven't worked on any really old Briggs in a while. Used to be able to get 
whatever you needed for them from Briggs. More than likely your local dealer 
can get what you need, just doesn't carry it in stock. The Briggs parts 
manuals are probably available on line.  Considering the number of  folks 
that have the David Bradley's, you would think there is a decent supply of 
parts. I imagine you are going to have to do a little searching to find some 
collectors groups. Best of luck on getting the old engine going.
