That's not a bad idea. But how can he differentiate good vacuum from bad? In other words, he'll pick up the PCV unless he plugs it off.@67Dart440GT can you put a vacuum gauge on the dipstick tube?

Yea you have to plug off everything and then test for vacuum at the dipstick tube.That's not a bad idea. But how can he differentiate good vacuum from bad? In other words, he'll pick up the PCV unless he plugs it off.
STREET AVENGER CARBURETOR - Holley https://documents.holley.com/199r10219-3.pdf
This is the manual for the carb.
Right. .....and I think it's gettin air from somewhere, too. We've gone over this in depth on Facebook and a little on the phone. He's blocked off EVERYTHING vacuum related on the carburetor and the intake and it still makes no change. That's why I lean toward the carburetor. If I had a good one for him to try, I'd send it, but I don't.
I agree, although pretty small since he removed and resealed the intake.There is still the possibility of a leak underneath the intake.

FYI I did not use the cork. Printo seals and rtv on the China walls.
I was going to start with my compression test. Then the valves next. I've been really busy lately. Tomorrow I will have time.Have you re-adjusted the valves yet ?

Vacuum gauge is your friend, - vacuum leak is constant, fluttering guage indicates fluctuating vacuum, a single, or many out of adjustment valves will cause that, as opposed to a constant leak, like a pcv = steady guage .

Years ago, a good friend introduced me to using a vacuum gauge to diagnose engine problems, in fact, it was often the first tool he would reach for when confronted...www.classiccarrestorationclub.com
I agree with this. Every time I have ever tuned the carb on this engine, even before I did anything to this the vacuum guage has always been low, and bounced 2-4 inches on the guage. It is never steady.Vacuum gauge is your friend, - vacuum leak is constant, fluttering guage indicates fluctuating vacuum, a single, or many out of adjustment valves will cause that, as opposed to a constant leak, like a pcv = steady guage .

They don't understand. With the camshaft your engine has, a vacuum gauge will never be steady. Ain't happenin.I agree with this.

I wish I had one. He'd have it already. I have this Eddy 750 that I cannot get to run right no matter what I do to it, or I'd send him that.Best to just swap a carb on and see if it runs. A regular old 600 Holley would do....

Those 750s have their own problemsI wish I had one. He'd have it already. I have this Eddy 750 that I cannot get to run right no matter what I do to it, or I'd send him that.
May be correct about the Avenger line but the post screenshot only proves the guy didn't know what he was doing and blamed the carb. Changing jets for an idle problem is silly, and that's being charitible.
