I cannot help with the 32/36 (banned from our shop); however:
You have issues with TWO DIFFERENT carburetors. Quite possible that the carb(s) are not the issue.
As Carl mentioned, there is a possibility of bad gasoline (it goes bad in 6~8 weeks).
I would suggest trying the auxiliary fuel tank with known fuel as Carl suggested. If that doesn't help, then a compression test, followed by an ignition test.
If the fuel doesn't help, the compression TESTS good, and the ignition TESTS good; then is the time to look at the fuel system.
