Normally you should be seeing well above 20 mpg highway, usually in the 25 mpg range if
everything is up to snuff.

I have a Dellorto 48 DHLA and no emissions or stock exhaust and I get 24-25 mpg normally. This is cruising on the highway. It drops to around 17-18 city and 10-12 in the
mountains

tell me more! im running a 48 IDA. Curious how to get some reasonable cruising MPGs

Your cruising mixture is dominated by your idle mixture. So make sure your idle
air adjustment is as lean as you want it. I think this is as true on the Webers as
the Dell. Not sure of the details for an IDA but thats where I'd start with it.

Oh and you have to keep your foot out of it. I normally cruise at around 3500 to
4000 rpm (75-80mph) and get this kind of mileage. YMMV LOL!
