more power (help)

Ok he’s fairly new I’ll give a chance. When you say timing is good. What does that mean to you are you referring to 10 degrees BTDC or you just saying it’s good? How did you make this determination? Did you use a timing light and factory manual to set timing. When you say vacuum is good did you actually put a gauge on manifold vacuum and determine a reading? How did you get to 3.5 turns out and figure that’s where idle circuit needs to be.
Used timing light and vacuum gauge. Well watched those be used when i first got the car. Both my mechanic grandpas got it to their standards, great. As good as they could get it
