Jet Heat Riser

The lever is in the down position currently. Does that mean that the heat riser is open or closed? Also, it appears that there should be a spring connected to the lever to move it. Where does the spring attach to the lever? I sense that it goes in the tiny hole at the end of the lever. Should it be open of closed when the car is running?

Please click on picture.

  • John, unless you’re planning on winter driving eliminate the heat riser. Make a block off plate for the front and just put a bolt and nut to block the back hole. I’ve done this on a Jet, and on both of my Hudson 8’s. In both cases the manifolds were cracked from stuck heat riser’s
