Ordered 3 rebuild kits and 3 brass floats for the Holley 1940 carbs. I know they're not your favorite David but makes the most sense for my situation. I will watch Mikes Carburetor videos before rebuilding. I've successfully rebuilt a handful of carbs over the years; I can only think of one that didn't work (an 1100 with a float needle that would stick) so any tips on the 1940 rebuild would be most welcome.
