Quote: That's a pretty big n/f spread using std bottle pressures in the 900 range. If that is a fresh start, I'd be closer to a 10-12 spread, 6-10* of timing pulled and start leaning it out until it slowed down. Then start feeding timing back in.
Car runs well and looks great.
I'm guessing the big spread from the higher fuel PSI ? I ran 6 lbs and had a 13 spread but prob. could have went a little more of a spread.
