Just pulled my Fairlady out of winter hibernation. This past winter I mated a 100k mile L28 stock block to an E31 head with mild port & polish work, new valve guides, 280z valves & an Isky 290/490 regrind cam. Triple 45 DCOE 152 [spain] Webers that are pretty new [from Evilc] and a header/exhaust from Sean Dezart in France.
I welded in a bung for a wide band O2 sensor but haven't plumbed the gauge yet.
specs for my triples
145 Mains
155 air correction
36 chokes
F16 emulsion tubes
45 accelerator pump jets
55F8 idle jets
4.50 auxillary venturis
Today while checking the above specs [hope I have ID'd correctly] I checked the idle mixture adjustment screws. From L>R they were; 2.5, 2.25, 2.75, 2.75, 2.25, 2.25 turns out. I only have a few miles on it but looking at the header coloring i have more blue in the middle cylinders than outboard. Think that's lean? When idling it sounds like it slightly missing [new plugs], pops when cruising along and pops under deceleration. It really pulls nicely and sounds awesome under mid to full throttle, once it climbs above 3k rpm's. My timing light is broken so I'm unable to check that and until I finish the wide band info is lacking. Currently it prefers rapid but not stomp on it throttle input and if I provide too little input begins to die. Ahh, the fun of sorting it all!
