Sounds great! I pine for overdrive (especially after driving 750 miles
or so in the last 3 days).

Folks may disagree, but I've found that the LESS you mess with the carbs,
the better they work. Either learn to set them properly (use the book
procedure) or get an expert to do it once... then leave them be for a
while (months, even).
The HIFs which were original to the 73 are pretty stable once you get
them set... the HSs seemed to be a bit more temperature sensitive.
The HIFs have the float chamber below the piston, the HSs have it off to
one side or the other.
I will say I did spend a lot of time tweaking my carbs until I rebuilt
the engine. Now I'm getting 22 city, 26 highway mileage (a tiny bit less
than the original figures) and decent power.
