Hearing what you guys have to say makes me jealous! I have a completely stock 72 240z and im getting around 14-15mpg city/highway mixed. Perhaps im running a little rich? The car runs fine except i have to get it pretty warm before i can let off the choke. Normally I have to drive it around for 10 minutes with the choke out so it wont bog when accelerating. I have a crane xr700 electronic ignition and a p60 coil on the way to my house via ups right now. Hopefully this will help some. I'll have to change my mixture settings. BTW I just got the car a couple months ago and i love it, except for the really crappy wet traction. My suspension is shot anyway... ------------------ Ben
