Tuning Help

[Camaro Zach]

Alright well i leaned it out to 12% and the smell went away. Hooked up a vacume gauge to the PCV port on the carb and it was fluctuating alot so i adjusted the idle fuel mixture to get it steady then i adjusted the timing and adjusted the mixture again. It idles great and doesnt really smell of gas. When you lean on the throttle it accelerates OK... but could be better. Then once you get up to speed and keep the throttle at a constant position it stumbles but if you hit the gas it recovers well and once you leave it at a constant speed again it begins to stumble. Does it sound like its too lean?



I'm going to pull the plugs when it cools off BTW

thanks for the help guys
