Hi :-)

i just got a 77 oldsmobile cutlass 2dr with a 350 in it. It gets 12.5 mixed. this seems a little low.

I made sure the vacuum advance was working, and the carb was recently rebuilt. At idle i think i hear a little miss, maybe a fouled plug or leaky valve?

my other car gets 45mpg and is faster, but i like driving the cutlass.
