Undisputed or Unhinged ?

That's the way I set my timing, period.

Can't go wrong.

if a 2 barrel didn't offer better average MPG, why did they offer them, especially on "economy" cars?

Cheaper to build. Many small 4 barrels have smaller primaries than a 2 barrel has. Keep your foot out of it and get better mileage.
