Why do I have high fuel pressure...

Thanks for the clarification Patrick.

Here I was thinking I've been doing it wrong for ages.

well, now i'm confused! should they both be the soft, paper thin type or the sl. concave very thin metal type? the picture from Holley looks like they're metal.

My current squirter, driven by the red cam, as noted before, is a 35, but i have several extra squirters, including a 31. suggestions? Bone stock carb (i thought) and stock 327/350 'Vette. thanx again. s

When replacing the squirter gaskets, both above and below, Holley recommends using Part #1008-844 in both positions. This is true even if one of the original gaskets looked a little fatter than the other.

I stand by my recommendation of an orange cam, using hole #1, and a 31 squirter. Blow out the passageway with compressed air while you have it all apart -- there's always a chance that a little piece of crud got in there.

OK, with a 31 squirter and the orange cam, the car runs well. The 35 had a sl. stall and the 31 is an improvement, but wonder if a 33 might be even better. (The enemy of good is better!) Might try that, but want to drive the car a bit more. However, of course it's raining, so I'm on hold. The start of all of this was the fuel pump on the Cobra and then a bad ring gear on the flywheel. Hope to move the Cobra onto the lift next weekend and get started on that project. thanx again. s

You know, with the orange cam you don't have to do that WOT .015" feeler gauge adjustment stuff that Holley and the manuals call for. Instead, while at idle, just tighten up the adjusting screw until it comes in to contact with the lever, and then give it another quarter turn or so to give it just a little bit of preload.

Yes, that's correct. Back off the bolt/nut combo just enough to remove the slack.
So many think it should have .015 at idle.
