Re: How can I improve fuel economy?
No need to go to fuel injection, just tune your carb. Get an Innovate wideband air/fuel ratio gauge to see how rich it is running, then re-jet accordingly. The timing will need to compliment the jetting too. You can lean out the accelerator pump amount until it starts to stumble, then go back up slightly.
I have a '64 VW bug that used to get 23-24 highway mpg with the stock single barrel carb. I swapped to dual Dellorto two barrels and it's gotten as high as 36.25 on the highway. It's never got lower than 28.5 city mileage since swapping and that's driving it hard. Carbs can get great mileage, they just have to be tuned.
