To add to our knowledge bank, here is what I learned about the main jets.
Correct jets for carburetor list number 7922 are number 59 jets. A carburator
specialist named "The Carburetor Factory" in Sacramento, California, looked
it up for me. (All they do is carburetors. Very helpful and friendly folks.
Telephone 916/339-3835. http://www.carburetorfactory.com
As suspected, the jets in the carb were larger: 65.
I bought a pair of 59 and a pair of 54 for good measure. When I took the bus
to the smog shop, I installed the 54s. Mistake! Too lean! The correct 59s were
what it needed to pass that part of the test.
It still failed due to an electrical misfire.
Working on that now.
