Weber Bypass Jets
 
Car runs fine, no flat spot if I accelerate taking it easy on the throttle. If I floor it, it gurgles and stumbles and then takes off like a bat out of hell. So I am thinking its the bypass jets in the bottom of fuel bowl. Do I go richer or leaner? The plugs are dark tan. I tried the 120 holders and 65 idles and the plugs were black.

331 small block
40 chokes
120 holder
60 idle jets
f5 emulsion tubes
160 mains
190 airs
50 pump jets
50 bypass jets

lean out the pump jets but I would invest in a LM1 to be sure

I have 0.00 bypass jets in my setup. Anything else produced a bog. Even tried a 0.35 bypass. If I step on the gas suddenly the wheels will snap and slip on the spot and if I am not carefull the car will go sideways, Such instantaneous is the response.
A little bit of black smoke maybe, but let be it if response is so fierce.
