Which Weber carb is commonly used on the 720 4x4's and what mileage can I expect?
A 32/36 down draft is good but a 38/38 will also work. I think the 32/36 is better driving and mileage almost as good as the stock carburetor as the secondary is progressive and only open above 60%? pedal. The 38/38 is more high performance and is too large in my opinion as it's for six cylinder and small V8 applications. Both barrels open at the same time so mileage and drive ability are not as good as the 32/36.
It's easier to live with a small carburetor and want a larger one than having a large carburetor and wish you had a smaller one.
