Carburetor loses prime after 8+ hours

Well I never did install the electric fuel pump, I went ahead and ordered a holley carburetor. I just got it installed a few days ago and it runs better than it ever has in 25 years. I couldn't be happier.

It starts up without issue every time no matter how long it's been sitting. It was a very easy install and since it is brand new, I don't have to deal with the reman carter bbd problems that may arise.







Now all I would like to do is get a more fitting air cleaner. I'm not liking the look of it.
