hi all..

need help with my heat riser.. this is in my 57 Fleetwood ... pic attached. it is stuck but can someone tell me if it is open or closed. where should it be for normal hot running?

Video is correct. My comments were a bit confusing anyway in reply below and replaced and bolded with the following: As the car is cranked cold and engine warms up it should turn clockwise opening up the butterfly.

Jason, when looking at the picture to open it fully you wrote counter clockwise, but 
shouldn't it be clockwise. When I watch your video you turn it clockwise to open it.

Are they all designed the same way?

thanks gents. I thought it was stuck open. thats where it needs to stay. we dont need that out here in Aus.  the 57 has the choke tube seperate to the manifold so the choke is more than enough for cold starts and its working ok. cheers

John,

It looks like it is open or at least partially open. When the car is cranked it should be turned with the too pins close together.  As the car is cranked cold and engine warms up it should turn clockwise opening up the butterfly.  If yours is stuck it is better to have it stuck open. You should be able to turn it by hand if it is not froze up. If froze up, sometimes you can saturate it with PB Blaster, WD 40 or other lube and free them up. Else you will need to replace it or make sure it is tied back fully open. Here is a picture of one I had stuck mostly open for reference (note the pin the spring attaches to and the one it stops against are separated like yours indicated yours is open):
