The air filter is the first place to start your quest for better gas
mileage.
2nd Fuel pressure too high or the carb fuel floats are adjusted wrong
3rd Check the power valve in the carb; it maybe leaking or is the wrong
one and is opening too soon
But if you are really happy with the performance of the car; don't look at
the fuel mileage just fill the tanks and drive.

Subject: Looooooow Gas Mileage Question
I don't drive the Tiger for its great gas mileage but I just
accidentally did the ultimate gas mileage test, and the results aren't
pretty. Filled up with 12.6 gallons (U.S.) of gas, I completely ran out
of fuel at 155 miles for an average of 12.3 miles per gallon.
The engine dyno'd at 250 HP a year or so ago, and I have a .73 5th gear
so rpms are around 2300 at 75 MPH, the usual freeway speed here in
southern Arizona. I installed a rebuilt vacuum advance distributor a
couple of months ago, replacing my old Ford dual point. I converted both
distributors to a Pertronix set up so the only real difference should be
the vacuum advance, which I thought should help with the mileage a bit.
I did clean my K&N air cleaner tonight, and it was filthy, so we'll see
if that helps with mileage with my next tank of gas.
Any other ideas on what else to look for?
