I bought my 390 Holley used and the PO had been playing with it untill it was so screwed up that he gave up. Now I'm trying my hand at it.
The Holley catalog doesn't list which power valve is stock in this carb (list 6299-1)
My questions are;
1. What number power valve came in your new 390?
2. If that one didn't work out, which one did?
3. Which color vacuum secondary spring was original?
4. If that one didn't work out, which one did?
5. The parts book said it came with .049 primary jets. If those didn't work out, what did?
6. Have you noticed any problems from "fuel slosh" with the carb mounted sideways (shaft running front to back)?
Any help will be greatly appreciated.
