Nothing wrong with the red cam if it suits the engine tune.



The white cam is the smallest in delivery at any change in throttle angle.

NO, i just explained it wrong. At the bottom of the nozzle/squirter is a small ? 1/4" gasket. it's torn. pump diaphragm is fine.

I've used that red cam for years, and the car ran great. I'll bet it's either the torn gasket or the vent rod was bent sl. out of whack. thanx. s

Right, there's actually two gaskets for the squirter. AND, the plumb bob thingy. That's still there, right?

Default Here's a pic

I looked it up. It's called the Accelerator Pump Nozzle Check Needle. Gaskets go both above and below the squirter.

correct. the lower of the two is a soft, flimsy gasket, the one between the Phillips and the squirter is really more like concave thin metal washer. Right? s

ADD: yeah, and there's the plumb bob thingy that looks like some needle and seat combos.

OK, you're all set then. Here's a pic though anyway. A properly functioning 31 squirter, and the regular old plain Jane screw (not the hollow one) will do you just fine. After all, you're not Morris hitting 190 on the straights....

Might be just me, but I don't like that nozzle to mainbody gasket, too thick.

Guess what happens to it as it is tightened down.
