hi guys, newbie here. help naman po mga gurus, i have a 1983 chevy s-10 pick up, long bed. V6 engine with automatic tranny and carburetor. the problem is the gas consumption. i know its a v6 engine kaya siguro ganun pero is there some tips and tricks to lessen even just a little bit the gas consumption of my pick up? im planning to swap engine pero nanghihinayang ako sa original, and good condition pa talaga sya. (running condition)

1. is having my carburetor overhauled would make a difference?
2. any idea where to buy carburetor repair kit?
3. do gas saver really helps?
4. kilometer per liter should be iin a v6 engine?
