Fuel mileage 32ADF vs. 34ADF

[kmoses]

I just checked my mileage after one tankfull running the 32 ADFA and my mpg has greatly improved. I got just over 23 mpg with the first tankfull!

Just returned from a round trip from Houston to New Orleans with a fully loaded trunk and the misses and my '77 with 34 adf averaged over 27+ mpg for the trip. Never had it apart so can't tell you what jets or tubes but runs great and purrs like a kitten on the highway.

This is great! I think we're getting some kind of consensus for carbed Spiders at about 22 city/27 highway. Assume results would vary depending on many factors, but this seems to be what people are getting. I see that Fiat rated my '77 at 19/28 when new according to one source. Not great mileage by todays standards, but I think most of us don't much care as we're getting exceptional "fun per gallon"!

is an Australian gallon like a UK gallon or a USA gallon ??

We use litres, haven't used gallons since the 70's. The data came out of a factory maintenance manual for the 131, so not sure which market they're catering to. There was a separate supplement for Oz delivered cars.

In case you're interested:
US gallon = 3.8 litres
AUS/UK gallon - 4.2 litres
