Chokes
Can anyone help me out on the proper way to hook up a bi-metal type choke? This is a coil type choke but it's heated by exhaust thru a 5/16th's tube. Not electric. It's a 2bbl Holley, except for the choke part I know them well, and I'm wantin' to put it on my 302.
So do I just use the exhaust manifold for a heat source, or should I figger some way to directly route the fire up there?

I don't believe you would route the actual exhaust up to the choke, but fresh air that is warmed by the exhaust. Most 302's had a fitting on the pass side exhaust manifold. I don't know though if this would be enough to make it work, since ford used this AND electric assist too. I hate working on chokes. They are very hard to get right when they don't work.

You can build a chimney from the exhaust manifold up to the choke to warm the choke up. On my headers they sent a 1" pipe with a slot on the bottom that allowed the pipe to be clamped to the header with hose clamps....however, most of the intakes have a choke plate directly under the choke that you can open up and put a chimney from the plate to the choke.

I found a passenger exhaust manifold with a boss on it for heating the choke. The tube's broke but I think some drilling and tapping for a new line will make it as good as new.
Thanks for the responses.
