Hello guys, just joined this site so i could get some help from u people out there. Have a 240z that i need to work on but little money to do it, so hoping u guys could offer some effective (but relatively cheap) ways to work on it. Im a big noobie at this stuff so all the help would be appreciated. For instance: the car runs fine and everything, but it always smells like its running rich all thetime. I checked to see if there was a fuel leak but that wasnt it. Do i need to tune the carbs up probably? what's the easiest way to do so?
