430B Holley 2010 - Carb Mixture Screws

[JagGuy]

Hi

The ends of the mixture screws are not perfect (that's an understatement) because I think someone torqued them down to 100 ft.lbs, rather than screwing them in gently until they stop.

Anyhow, I need new ones and even though I have the parts list for the carb, it does not list part numbers. If there is a parts list with numbers, I can't find one.

So far, carb suppliers have been no help, other than to say "Holley didn't change their screws much, they are probably all the same"

Does anyone know the part number of the screws?

The Holley #26-101 is quoted a lot. Mixture screws for 2300/4150/4160/4500 are all apparently this number.

Any ideas anyone?

Thanks . . . Brian

P.S. For what it's worth, I attached a before and after of my carb rebuild. I know the spring is attached incorrectly, it was a temporary thing, now changed.

May be worth either calling or e-mailing Holley about this. The should be able to tell you what you need exactly;

Thanks for the info and the link - that's exactly what I'll do.

Now . . . I should have thought of that . . . .
