Re: IML: Heat riser rotation?

[randalpark@xxxxxxx]

If it isn't stuck, the pressure of the exhaust going through will 
easily keep it open when the car is running. The main objection would 
be to the noise that it makes if it requires servicing/and or some new 
parts. Wiring it open is probably a good thing on seldom driven cars, 
since being stuck closed is serious, and not being moved for extended 
periods is one way that can happen. Still, an occassional squirt of 
penetrating oil will keep it free. Functioning, it does help open the 
choke properly. On both the 413 and 440 engines the choke spring is 
housed in the intake manifold, and requires the heat (in concert with 
the choke pull off) to allow it to open.

I did this on my 69 LeBaron. I put a ss hose clamp on the exhaust pipe 
just below the valve. The screw part of the hose clamp holds the heat 
riser valve open.

Dumb question time:

On a '67 440 (from an Imperial - required
content), looking at it from the passenger's
fender, which way does the heat riser rotate as
it opens? I suspect mine does not work
correctly and I want to wire it open.
