[AMC-list] 1981 Spirit 6 cyl air intake trap door vacuum motor failed (more)

[gqrxzy8974@xxxxxxxx]

This was previously posted on amcyclopedia.org but didn't
appear as I expected on the amc-list, so I'm reposting
it directly to amc-list with later information.

I've a 1981 AMC Spirit 6 cyl and the air intake trap door 
vacuum motor has failed. The vacuum motor doesn't move
with vacuum applied and doesn't hold vacuum either.

The trap door moves freely (not bound up) and since it 
opens in toward the carburetor intake, perhaps the engine
air suction also opens it since the car runs (mostly).

Is there a source for a replacement (or is it possible 
to repair?)?

I've since removed trap door motor and uncrimped it to
open it.  The internal rubber diaphragm has a small tear
in it at the point it folds.  I've thought of patching
this with some sort of glue (no patch, just glue).

Searching on the web I found hits unrelated to AMCs 
but for other diaphragms suggested either gorilla glue
(polyurethane) or Permatex Ultra Black Silicone.

I'm also thinking of annealing the single metal part
which gets crimped to try to avoid the crimps breaking
off when recrimped.

Any suggestions or comments?
