Found a Quadrajet

[blazer74]

Have you received Cliffs book yet.
Invaluable.
Should read through it and will give a new perspective and knowledge.
Cliff can supply all the parts you need and advice. He has a forum and I would assume you can still call him.
I prefer to run the the 76 and later APT (adjustable part throttle)carbs. They are a better design and can be electric choke.
Originality is important also.
An issue you may have is the porous casting in the float bowl can cause fuel to seep through the casting causing problems as well as the casting plugs.
The needle/ seat where it screws into the housing also.
Good possibility the idle tubes and idle channels are clogged or restricted with crud.
This is all covered in Cliffs book.
That little lever thing you were pointing to in one of the pics is an early design APT. Set at the factory.

Thank you so much.
Yes, I received Cliff's book.
His shop is only 70 miles from home.
I am about half way thru Cliff's book.
I also have 4 other manuals.
Some good, some not.
I would love a chance to spend a weekend with him to work on Qjets.

Update:
Ordered a choke pull off vacuum actuator.
And it won't slip into the bracket.
And here's why...:
My bracket is made from .090 thick steel.
The actuator's groove which is supposed to nest around the bracket is only .073.
It's .020 too small.
Gotta make a phone call....arrrgh.

Good news.
I called the supplier of the pull-off.
He requested some photos and I sent a few showing the difference.
Apparently, this was a first instance of the issue and after he checked things out, a replacement has been shipped.
Kudos and 10 stars to Carbs Unlimited.
Thank you, Steve. A good guy.
