Post subject:  Couple of dumb intake questions
Working on my daughter's 1964 Valiant /6 - 225
With the help of this forum I got it running and stopping.

My problem is that it takes a loooong time to warm up. I'm in CA so cold weather isn't a major issue and the car is always garaged.
The warm up problem leads me to believe it's a choke and/or manifold heat riser issue

Question1:
The heat riser moves freely. It's not stuck.
Can you tell me which way is open( heating intake) or closed (not heating intake)
Here's a picture standing at the front of the car. At dead cold, the round counterweight seems to be all the way to the right.
Is open turned Left or Right?

Question 2:
Is my choke plate fully closing? This is at it's stopping point. Seems like it should close a little more (adding electronic choke kit next)
Image

Question 3:
What is this tap/port for?
Image

BTW: Here's a pic of my 17yr olds first car. (i'm a better at paint/body than the mechanics)

THANKS IN ADVANCE!!!!!

Picture #2

Looks like a bad choke thermostat could be causing the choke not to close. I believe that style should not have that bend in middle of the connection rod.

That is the non-electric OE style thermostat.

The electric conversions are available and popular. Still using an OE style on one car that works fine.

Should the choke plate be closing more? seems to stop (wont go further) than what the picture shows.

Also, already bought the electric choke conversion.

Yes, choke is misadjusted or has some fault with the linkage. or tstat It should move so that it completely closes off the top of the carb throat. Try disconnecting the choke linkage (with little L-shaped clip) and see if it will close, then go downstream to the other parts of the linkage and choke tstat.

To answer your other question, the heat riser is in the correct position for being dead cold. The knob should rotate to the left (counter-clockwise) when it warms up. There's a curved piece of sheet metal inside which, when cold, mostly blocks the exhaust from going straight down the downpipe and directs it up against the bottom of the intake manifold. When the assembly rotates left, what was the leading edge of that sheet metal piece moves to the right and becomes the trailing edge. It then (mostly) blocks the gas from hitting the intake and directs it down the pipe.
