The Fordor is a heavy Model A, and with mine, driving in town all the time, with lots of stop and go driving, I only get about 15-16 mpg. On the open road, and cruising 55 mph, with overdrive, I get 20-22 mpg. 10 mpg sounds quite low, even around town. Once warmed up, you should not have to adjust the GAV (not throttle). All Models are a little different, but many seem to like 1/4 turn open after warming up. I would do all the basics first: Check your points and gap, check the timing, pull spark plugs, maybe replace, clean and gap those. Another place to check would be your carburetor….make sure your jets are properly size. And at speed, your spark advance should be at least 3/4 down.
