My experiences with "old" gas (including a '67 E-type that I no longer own
(NO, I DON'T want to talk about it)) are different from what's described in
this thred.  For me, old gas made it harder to start a cold engine, and
made the engine seem a tad down on power, but the engine ran well enough
and even had a pretty steady idle.  I have two suggestions re: your 120:

(1) sell it to me, cheep, or...
(2) top the tank off with 'fresh' premium gas.  If its just 'old' gas I'll
recon you'd see an improvement with fresh fuel.

I really think option one is the best for you  ;-)

My take on the clogged lines and filters is that if there are bits (rust?)
in the lines that are pushed along with the fuel, and 'pack' at some point
in the line (or in the 'dirty' side of the fuel filter), that packing
breaks down when the fuel preasure drops to zero (when the engine is off),
clearing the block temporarily.  After starting the engine up again, fuel
flow repacks the block and the engine starves again.  

YMMV,
