I was talking to a friend of mine about carbs and such and i was talkin about gas milage and air/feul ratio

he said something about tuning the carb... how would i go about doing that??

 

Check out the FAQ section...here is one link in that section

May also depend on type of carb you have but general information is a good place to start.

 

If you tune a carb for milage you lose power. You can only get it so lean on the cruise without sacraficing the AFR at WOT. If you go lean enough for good mileage, then you lose some fuel and don't make as much power. But you can still get decent mileage and power with a carb if everything is set up right
