Zip,

When we changed from carb to injection back to carb. When we made the switch we worked with Rupert that way we did not have to have the regulator and bypass. We drilled the pill until the fuel pressure was correct.

That's one way too do it, but actaually there's an easier way. You can use an idle bypass valve/poppet. They come with 3 or 4 springs and shims ranging from 5 to 20lbs. I don't know how much the carb seats will hold, but i'm guessing 10 to 14 lbs. You can choose a 10 lb spring and useing a leakdown gage set the poppet to your target by useing the shims provided with the idle bypass valve.

Zip.
