Hey there Denny: Those are pretty grim gas mileage numbers and I'm sure a lot of that is due to that 4:57 fanny in there.

I got one thought (that's about my daily limit now) as I read this thread. Timing on the mark is what the book says, but common practice is to give it as much advance as she'll take without pinging. Also, check your vacuum advance, when you rev the engine does it move? More advance = more mileage. Other than that, what brand of gas do you use? (I'll buy a few shares of their stock) grin
