OK...I'm pretty sure I installed my NORS heat riser on the 63' 289 correctly. I even filed down the inside of the pipe so as to have a clean action without rubbing.....so: I think the thing is not working correctly. I say this because the weight doesn't move no matter what temperature the engine is. Absolutely no spring action at all. When installed and looking down and from the outside, the counterweight is sitting covering an position of 6-9(on the clock). In this position, the weight (cold) holds this position. If I rotate the weight clockwise to about 11-2, not only will it hold in that position (it can stick) but I get the nice throaty dual sound of the exhaust going down the road, especially with deceleration. NOW: Do I have this installed wrong ?? More specifically: when the thermostatic coil gets HOT doesn't it expand and spread out moving the weight ?

I think you have installed it upside down the way you describe it. The weight when cold should be at about the one or two o'clock position, as the spring heats up the weight will drop to about 5 o'clock.

Yes it is upsidedown, but the sticking could be the butterfly hitting the Exhaust Manifold, and you will need to grind a little off of the heat riser butterfly to correct it.
Is this NORS one, the Repro with the half round counterweight?

HOW ABOUT THE HEAT RISER FUNCTION ON A 185CI, 6CYL.....WHERE DOES THE HEAT RISER GO...DOES IT GO TO THE CARB.?

It does not connect to the intake manifold, it merely heats it.

OK, WHAT ABOUT THE SMALL PIPE COMING OUT THE TOP OF THE EXHAUST MANIFOLD ON THE LH SIDE, FIREWALL SIDE OF THE CARB.

O, I HAVE CLEANED THAT OUT, NO PROBLEM.....I AM INQ ABOUT 1/4" PIPE THAT RUNS THROUGH THE EXHAUST MANIFOLD, AND COMES OUT ON THE FIREWALL SIDE OF THE CARBEURATOR...., SHOULD THAT RUN INTO SOMETHING?
It may help to consult Pg. 10 of the Engine Section of your 1955 to 1958 Studebaker Chassis Parts Catalog for a pic. of the Intake/Exhaust Manifold.
You cannot maintain a Studebaker without using the Shop Manual and Parts Catalogs.

On most 6 Cyl. engines, there is another tube with a enlarged end that slips over the one in the manifold with a big curve at the top and a flared end with a compression nut to allow it to screw onto the threaded nipple on the Auto. choke housing.
