Thermoquad rebuild.

Yea I know but chances are a poorly tuned and or rebuilt carb isnt gonna fire up and run. Thats what I was getting at. Setting there cranking blindly trying to get it to start not knowing whether it's the carb timing electrical etc. I'd rather eliminate as much of that as possible by starting with a well known carb.

Ummmmm

You realize I’m not arguing the point or idea nor pushing you to break in the engine/ am with a freshly rebuilt carb?

Why am I even here?

a known working carb is needed for initial fire up, but rest assure there have been many engines shut down after initial fire from other unforeseen problems. It happens, like I said, too much made of cam break in.

Absolutely! A good carburetor just means there's "one less" thAng to go wrong. ....and who wouldn't want that?

Yea I know I wasnt implying that you were! I was just saying that I understand the endless cranking of an uncorrportive engine is what wipes the lobes. And I would like to avoid that at all costs lol

Agreed and with my limited experience I want to eliminate as many obstacles as possible. Thats why i bought a new mopar ecu , mopar distributor, new plugs wires rotor cap, basically the only think missing from the big "Three" is a new carburetor.
 
Hey @RustyRatRod few more questions if you dont mind.
1) for my build a mild 360 would you recommend a large or small primary tq?
2) what parts between the two are interchangeable?
3) you mentioned before about the distributor advance port being able to add one. Hoe exactly is this done?
4) I found a diagram for the vacuum ports what goes where etc. Can you dummy this down for me? What do I need to use and what gets plugged etc.?
I'm sure I will think of more later lol
Thanks buddy.
 
That was rumblefish that talked about adding the ported vacuum inlet. I've never done one. I've always just hunted for a TQ that already had it. They're plentiful. Not hard to find at all. They have a small brass tube sticking out of the plastic body on the passenger's side front of the carburetor. It was actually used for the EGR, but it's ported vacuum and that's what the distributor advance needs so it's perfect for that. Most all the parts will interchange. You can change the main body and base plate out if you want to go that far.

For your mild 360 the 800 will be fine, but if you have or find an 850 first, run it.

Ok so the brass one is the one that the distributor goes to? I thought it was the one to the left of the idle screw. Are both of the screws idle mixture screws? The diagram that I have only shows one screw mine has two one on both sides of the pcv.

Yes they all have two mixture screws in the front. The thing to keep in mind with ported vacuum is, it has to be a vacuum inlet above the throttle plates. The brass tube is the only one on the TQ. All the others used manifold vacuum.
