The '34 Roadster works pretty well. Ignition is adjusted. It's easy to start, pulls evenly and good, no stumbling. The idle is maybe a little high, even with the adjusting screw all the way out, but all in all the engine works well.
But the AF ratio is way too rich. Crusing around 12-1500 rpm shows 12-12,5:1.
QFT Super Street (Holley based) 650 CFM DP carb.
Engine is a Chevy small block mainly standard except air gap intake, headers and 2 x 2,5" exhaust, straight thru mufflers.
6 speed trans.
What do you suggest? Lean down the primary jets a bit?
If so, how much? 3 steps?
