I've finally got it running (somewhat). It's really cold-blooded. It wants to idle very fast when cold and chokes are engaged. It wants to idle too slow if I hit the gas to release the choke. Once everything warms up to operating temperature it seems to idle and accelerate ok.
I think my problem is with the hot water heat. It's not hot when the motor needs it to be hot.
Anyone try to run exhaust heat through the intake? How did you do it? Did you use an EGR valve? Will that work? It seems exhaust would get hot faster than the water. What do you guys/gals think?

It seems to me that the water doesn't warm fast enough. Why wouldn't an exhaust solution be better? | | | | | Joined: Jul 2003 Posts: 141 Member | | Member Joined: Jul 2003 Posts: 141 | I have 2 of the Langdon carbs, his linkage, and his water manifold heat setup. It was basically a bolt on and use project. I wired both the chokes and they seem to work great. This is installed on a '62 261 with 848 head and Howard's cam in my '52 1/2 ton PU. I had one question before installation and Tom was very helpful.
Good luck with your project...it's worth it!

These manifolds arre intended for exhaust heat. Ed Graham on this site has made some alum plugs to weld in so water heat can be used. Do a search.

Tell me more. Did you just run a tube from each header to the manifold heat block? What size tube? What diameter? What material (steel, copper, aluminum, etc.)? Did you put any kind of butterfly on one header to force the heat through the intake? Thanks.
Jerry | | | | | Joined: Feb 2001 Posts: 4,095 'Bolter | | 'Bolter Joined: Feb 2001 Posts: 4,095 | i used a plate from langdons. no butterfly, seems the copper conducts the heat just fine more i think than the heat flow. they get hot quick. pictures late. ron
