I'm guessing that you don't know what size jets are in them, so you have to 
take the top off to find that out anyway.  With our ethanol fuel, you 
probably want to go to 51 or 52 jets.  A rebuild kit is $20 or so (including 
a new accelerator pump) and if throttle shafts are needed, that's probably 
about another $15 each.

'65 or 6 carbs seem to be favored.

If you have the Junkyard Primer - check pages 19 and 20 for help with ID, 
but it sounds as if you pretty much have that info in your head already.
