Help with carburator
352 V/8-stock (66 Ford) stock FoMoco 2 barrel carb.
What size jets for 5000/6000 feet in elevation?
What size power valve?
What size accelerator pump ( so as not to pump to much or to little gas down inside)?
Have a friends truck with some running issues.
thank you.

Where in CO are you? I'm in Littleton. I have the same setup. At some point in the past someone replaced/rebuilt the carb, but it's still a 2100. I've adjusted it quite a lot from what it was and it runs pretty well. I don't think you need to do that much to them. I also have a 2150 on my '74 Scout and it runs just fine without getting into the internals.

Mark,
The part numbers he posts are from dealers from all over the place. If you decide which ones you need, he will usually post a couple places to call for those ones.

See what Cory typed in post #5.
I have nothing for sale, I look up the part numbers, then search for them, post what I find. In this case, there are multiple sources that have each of these parts.
Pick out the part numbers you want, I'll list some of the sources.

Think we have it figured out...
Ok guys, here is what I think I have found.
Everything checks out with the new carburetor and related tune stuff however I have a vacuum leak that seems to be internal or related to the phenolic plate that sits between the manifold and the carburetor. I have had this problem once before with a similar plate on another ford engine. That plate had fissures and or cracks it it causing vacuum leaks. I replaced the plate and problems were solved.
In this case the leak is on the right or passengers side of the carb, drop in vacuum might be responsible for allowing the PCV valve to stay open causing the intake to pull more air from the crankcase instead of through that bank of the carburetor.
Here is my question.
Where can I get a good aluminum or replacement plate like the one used on this engine (352 2 bb carb), that also has the port for the PCV valve? I am guessing that the old Bakolite is toast on the one on this engine and may also have hairline cracks or fissures in it.
