Thread: Mouse MPG, What to expect?

Tweet

Hmmm. Dual quads and a heavy foot, combined with some idle time and a bit of around town cruizin' could well equate to 10 mpg... Try some just down the road driving, keeping your foot out of the secondaries, and see how it does...
What size of Edelbrock carbs do you have on there? You don't possibly have a choke hanging part ways closed??? Is the linkage on the carbs progressive, and could it possibly be adjusted incorrectly allowing the secondary carb to open up too soon??

Performer series, 500, no choke hooked up yet, linkage is not progressive
THX!

Not progressive linkage? If you're running dual quads on straight linkage then both carbs are working at all speeds and 10 mpg might be about it!!!!

Progressive linkage will make a big difference in your gas mileage. When I ran dual quads many years ago, the front carb did not have an idle circuit, and it was used only when you mashed the throttle. Everything ran off the rear carb.

Ah, that says a lot. I ran the dual quads on my 27 with straight linkage for the entire time I drove it, and while it ran well the gas mileage wasn't all that great. This time around I've added progressive linkage and hope it gets better. I would also think your car runs a little rich, I know mine did.
