Hello all. First post.
1964 Valiant 225 w/BBS carb

I just picked up this car as my daughters first car (she's 16)
Car is a runner/driver but she's running a little rough. Just installed new plugs, wires, cap, rotor, points, air filter and changed all the fluids... time to tackle the vacuum lines.

The vacuum lines should be pretty straight forward for this engine. One hose from base of carb to PVC valve. One hose from distributor to vacuum advance fitting on the carb. (and of course the breather to air filter line)

(See pictures)

Question 1:
Why would some one install these plastic check valves? Should I get rid of them and just run a straight hose for each (vac advance/PVC)?

I couldn't understand why there is a T-Connection until I noticed that the distributor line fitting on the carb is either broken off or removed (see picture). The hole appears to be blocked off with some kind of rubber stopper.

Question 2:
Can this fitting be replaced? Is it a screw in fitting? Where can I find the part?

Question 3:
If it can't be replaced, should I continue to run it in the current T-configuration? '


Thanks everyone in advance!

Eeyikes! That's about 200% wrong. Best scrape off that hacked mess and put it together correctly. The carb's missing vacuum advance port can easily be replaced if whatever gunk was used to block off the hole for it can be removed.

You'll want a new choke thermostat, too; the one on the car has had its pushrod crudely bent, which never makes things better. The original-type units are no longer easy to find, though Old Car Parts Northwest might still have some. If not, you can use a № 1231 Electric choke kit.

PCV valve looks multiple decades old—that's a very early type. No longer easy to find, but send me a Private Message on here.
