Update: Received Carb kit which I knew would have the choice between two different interior gaskets. When I recently rebuilt the carb, I believe I matched the gasket with the old gasket. However, I never knew for sure if someone in the past had made the wrong selection. This time I would like...

I'll check that out when I inspect the carb this week. Keep in mind I rebuilt the carb already it and has zero miles on it since then.

It may be that the current rebuild kits have the correct X rings.

Update: I replaced the PCV and power brake hoses with 11/32' hoses and worm clamps. Cold started the 340, ran it until the choke almost opened completely, and kicked down the fast idle to curb idle. Put my hand over the carb airhorn and the idle did not change. I thought "whoopee", wont have to...

Update: Looking at what was packed inside the tachometer box, I found a small strip of red tape. Taking an even closer look, I noticed four individual "arrow" cutouts. I used one of such to mark the red line on the tach at 5,500 rpm for now (photo #1). The three metal wire connectors for the...

That's what I thought and what I have seen in the past. The '72 has a extra hole right below and a little forward of where the kick-down rod is attached where I see the spring in the post photo #1. Don't know if the factory put that hole there for the model year for the spring or not.

Found this photo online showing what appears to be two springs on the Thermo-quad kick-down linkage (one green and one reddish). Is that correct or was someone just getting carried away with it all Thank you. P.S. And is the throttle return spring clipped in the right spot?

When I sprayed the brake cleaner near the hose, there was no tie wrap yet (hose just pushed on). I just put that tie on today during the diagnostics. But I should check out that hose more carefully. Maybe remove it and plug the fitting and spray again?

Update: Putting my hand over the air horn and the idle speed increases noticeably. Same thing when I spray brake cleaner at the base of the carb between the two idle screws. Ordered another carb kit from Rock Auto today (Walker 15543C). I did find the 10 or 12 carb screws were rather loose...

I'm always debating with myself regarding studs vs bolts. I wonder what the '72 factory Thermoquad used for fasteners?

Update: Did some detective work. Warmed up the engine (starts fine with choke set). Attached a vacuum gauge. Sprayed brake cleaner around the intake ports (no change) and around the base of the Thermoquad (idle speed increased significantly). Place my left hand over the primary are horn after...

Renteria Brothers ran my all steel body vehicle from about 1980 to 2000 when they sold it to Kenny Moorhead. The four door "Valiant" they have run since then is not a true Valiant at all, but something with a plastic/fiberglass/composite body. Here are photos of my car when sold in 1980 (1974...

If I'm not mistaken, I believe that is what I used when it was inserted (but it was awhile ago so not positive).

On a small block anyway the tube fits directly into a hole in the front of the cylinder block. On the left side near the small core plug in the photo.

When I re-inserted the same dipstick tube in the 340 I rebuilt, sure enough it was a tad loose. Now that it's installed and running in the vehicle, it wants to just fall on out. The silicone or whatever I used to secure it was a complete and utter failure. Any leads for me on a decent...
