Propane / Dual Fuel Question.
 

I have a dual fuel setup that I believe to be almost as old as the truck (1986 F-250 460 w/Holley 4180 carb). I am having some troubles getting it to idle right in propane mode. It runs great on gasoline. Does anyone know where I can find some maintenance information for this setup. I've done a lot of searching, but I haven't found out much.

I have an IMPCO Model "E",

and a "Century" model 2610 mixer, that looks like it's made by Borg-Warner.

Thanks in advance for any help.

I don't have any experience with this mixer but there are others who have. Try posting your question on a propane forum.

I work with propane powered small engines. One of my sources is LE Klein in Texas. They are pretty sharp on this stuff. What kind of symptoms are you having, specifically?
