Install a T fitting on your Vacuum line.Then run a line Thur the firewall
to your dash. Install a manifold vacuum gauge on your dash.When you are
driving the needle should hold steady.Accelerate the needle will move one
direction. Using gas.Let off the gas. The gauge will move the other
direction.Saving gas .If your engine is not running right.The needle will
jump around..My 64 Pontiac had a fuel economy gauge on the console.That did
the same thing.
Easy way to test one if you don’t have a vacuum tester is to pull the rod
then hold your finger over the hole and if the rod stays and doesn’t drift
back it is good. From what you were showing it still looked like your
diaphragm has a hole in it, since it should have sucked in and stayed until
you released the vacuum from your tester.
my father had the same hood ornament on his frieghtliner semi as you have
on the rat lol sounds alot better starts alot better waiting for the next
vid
BTW, the vacuum advance normally works at idle not on acceleration. That is
why most manuals will tell you to disconnect the vacuum advance when you
are setting your basic timing with a light. Hope this helps.
Remember when you put the timing light on it to block off the vacuum first,
Adjust the timing and then re-attach the vacuum line. If you set the timing
with the vacuum advance attached, you will over advance the timing and
reduce your low end power. 🙂 but I figure a smart guy like you knows that
already.
White shirt mechanic – that’s high class!
Diaphragm is shot in that one too… it doesn’t hold vacuum. (Unless your
vacuum pump leaks.)

glad to see things working out for you.

Maybe you can fix the old one with oil too.

Not trying to be a “know it all”, just passing on some of the knowledge I
gained working as a mechanic back in the day.
epic nice vid man
Can you say “dwell meter” lol works great for vacume systems
Like someone else said, that vac advance is pooched too. Are you using a
ported source for vacuum ? Great video like all you put out! Thanks
That’s a thought… but I do have her runnin’ pretty good now..
Looks like your getting the engine closer to ideal, do you think the
electronic ignition has made a difference ?
I can see you know what you are talking about, and you put it in a clear
way. Ive now learnt something i didnt know, thanks 🙂
No, you’re not spam. Yes, there is a HAMB plate on the firewall. One on the
inner fender well of the Rambler too..
More powerful than a locomotive too..
Great video! I’m glad its working now!
did I see a HAMB plaque in there? (let me know if I still come through as
spam?)
Thanks!
Yea, you don’t see them vacuum gauges much anymore, but back in the day
they were pretty common..
You are welcome. Only always trying to help, not be a “know-it-all”
I was just about to say that aswell lol
I think so, but can’t say for certain. Didn’t notice any difference at
first, but as I tune on it, I think it’s runnin’ better than ever now..
is it on your vacom advans side of the carby
looked bad to me too
Is what on my vacom advans side?
