In most vehicles the engine will slope to the rear in order to better mange the angle between the transmission output shaft and the rear axle input shaft.
If you are getting 15 mpg your engine is running pretty good. Carburetors are relatively inefficient with respect to managing the fuel to air ratio and properly atomizing the fuel especially when compared to today’s fuel injection systems.

I would say it sits lower in the rear due to incorrect transmission and front motor mounts. The 1934/1935 engines sat almost level. 1940 was the first year for the engine to set noticably lower in the rear. Then even the cylinder head had better oil return holes to the rear for better oil return to the sump. In long distance straight open highway my 1934 Master would give abut 17-18 miles per gallon at 55 MPH ...that is with US 4 quart gallons.

I assume New Zealand uses Imperial gallons?
If so... Gene's 17-18 mpg converts to about 20-1/2 to 21-1/2 mpg with the Imperial 4 quart gallon.
And that's about what Dad said they got with vehicles from that time up here in Canada.

There is a descrepancy in liquid measure conversion 1 US gallon is close to 4 litres but the imperial gallon is closer to 4.5 litres. Tony

No discrepancy.
An imperial gallon is 4.54 liters. A US gallon is 3.785 liters.
That means you can use 5 to 6 ratio and be very very close.
Even though one would think it would be otherwise due to the Imperial quart being 40 ounces, and the US quart being 32 ounces, what many people don't know is that the 2 systems use DIFFERENT ounces. And of course, both have a 4 quart gallon.
