  1. hey guys so i just recently got my 75 280Z up and running, and actually drove it around some, needless to say, i'm stoked. the only problem is that the engine backfires any time i try to give it more than a little gas. if i press on the gas slightly, to allow the rpm's to creep up, it's fine, but any time i step on the gas with any real force, the engine sputters, backfires, and loses power.

I have a stock 73 240 with the exceptions of a lightened flywheel (5lbs taken off), roundtopps, a turbo oil pump, and just recently a zx dizzy upgrade. I rebuilt my l24 600 miles ago and have been tinkering with tuning carbs and ignition timing and it just doesn’t seem right. I just replaced the oil today from the 30w break-in oil to 10w-30 valvoline vr1. Compression test showed 150psi in all cylinders. Ignition timing is set to about 10.5. I am a newb and this was my first
