afc diaphram location
where is the afc diaphram? Will it make your boost curve change? How does it go bad and can I buy a new one?

also, you can adjust your boost curve by sliding the afc, star wheel and the smoke screw.

The diaphragm is under the far right part here


I've seen diaphragms spring leaks, when it happens it is very obvious-- no power.

Why would anyone put a plastic bottlecap under the AFC top above the diaphram?
