The data I have for a 40795A is that it should have a 54413565 vacuum unit,
with specs of 2-6-3 (normally marked on the unit). Meaning that advance
starts at 2 inches of mercury, and ends at 6 inches of mercury with a total
of 3 cam degrees (6 crankshaft degrees) advance.
YMMV ... if anyone knows different, please let me know.
