Does anyone know how to..or...have done this?

My wagon is running rough after a hot start or after running in the heat for a long time...felt like vapor-locking mostly. Go to find out that Subaru used something called a "F-1 Kit" on the ea81s...Hitachi carburetors..a device that was installed in the engine block itself and helped keep the carb from overheating from the block heat...don't remember the details exactly..but..my wagon is not equipped with one...hence the "vapor-locking". Not the typical vapor locking that normally happens when the fuel lines overheat and cause the gas to percolate and then the car runs rough or dies....so with that said..here is the question:
Has anyone designed/built a carb heat-shield/cooler? A plate that could be installed between the carb and intake manifold that would use coolant from the radiator to cool the carb. I have a new radiator that has the automatic trans cooling lines that are plugged because I have a 4 speed manual trans..so if I just somehow fabricated a shield/cooler and a pump of some sort to channel anti-freeze/coolant to and from the radiator...there ya go...maybe the first of it's kind...eh? Does anyone know where I should start in order to make the shield/cooler device? Mike said he has never seen one..so...think I'm gonna give it a shot.
Also want to say thanks again to Mike at S-Wings...and Diamond thanks you too.
Any input on this idea is greatly appreciated.:smokin:

I think radiator-temperature water would still be too warm for your application. The fuel will still boil at those temps.
Would dropping the float level in the carb help alleviate symptoms like this? Anyone?

I suggest the carb be bolted down to a wooden or phenolic spacer, like SOOBME suggested. I'd avoid aluminum anything, because it's gonna conduct heat too good. Insulate the fuel lines from engine heat, maybe with the fiberglass material GM puts on hoses that go around exhaust manifolds. Cool air from the front of the car, feeding the carb or just blowing on it, will cool things off in general. I think the insulative spacer will do you the most good.

Anyone know if this is some sort of fix for that?

But if moving the fuel pump is a fix, well, that sounds easier.
