Whole sells a rebuilding kit for the Holley 715 cfm carb that has all the right parts in it. Part stores sell you a 4150 kit and it does not have all the right parts you need. Thanks Mike
I've bought them from Tony Branda in the past. http://cobranda.com/ several other possibilites: http://www.shelbyparts.com/ http://cobraautomotive.com/ http://www.ponycarburetors.com/ Z. Ray '66 GT-350
A couple of years ago I bought a complete kit from Daytona Parts Co., 386-427-7108. It had everything including a correct LeMans needle & seat, part# 442. I was referred to them by Holley tech support.
Have never found a kit that included the correct power valve #85, i.e 8.5 Inches of Mercury. Always had to buy that one separately. Texas Swede
