carter carb function

I did the ECM Test by pass and installed the ford conversion . The 2100 was also jetted for the 258 by the rebuilder . Starts every time no matter the temp or weather .

I know the Carter has no power valve, I meant the knockoff 2100 I bought.  The Carter uses metering rods and a vacuum piston.

The power valves are rated strangely. Their numbering system is actually the inches of Hg that they open at. I prefer running a 45 most of the time.

45?!  Does it EVER open?  haha

[carnuck]

On hills mostly. 17-20 mpg is nothing to sneeze at! (not a stock cam)

Maybe I don't understand the rating, but I've never seen 45" of vacuum generated.  4.5" would make sense to me, as that would be under load, when you'd want the valve to open for enrichment.

[carnuck]

4.5" is correct but they number them 45 (like I said it's weird their numbering system) Jets are even more fun because the number describes the shapes as well as siz.

So it's like the Carter jets.  092 minus the decimal point.
