Any parts (kits floats choke pull offs elec choke conversion kits) Where? I went and looked thru a phone book sized Holley catalog at the parts store, that does not mention these carbs even in the "parts" section; also the only number I can find starts with an "L" yet all the Holley carb numbers in the book started with an "R" when I went to look for a rebuild kit. I am considering using one in a Magnum head conversion on my 83 D 250.. Have 2 of these carbs, that need gone thru; Daily driven, heavy truck, not "used" as a truck ~85% of the time, looking for "just that little bit" more power while retaining the same or (hopefully) better fuel mileage. Dead stock, unrebuilt shortblock; though with the Magnum heads I will be using 1.6 Magnum valve gear. (will "wake up" that stock 318 2 barrel cam, even if just a little)

Then I changed it out for a Holley 500 CFM 2bbl. The Economaster is very good on gas. I believe they are 300 or 350 CFM. Should have no trouble getting at least 20mpg or better on the highway with one of these. I had a lot of good luck with this carb. I still have it in a box. I can't tell you the performance difference from the original Carter 2bbl carb. When I got the car in 79' the Holley Economaster was on it. Set up right it will spin the tires but it will not pin you to the seat with the acceleration. It's just a gas mileage carb. Borg Warner lists carburetor parts for Holley's and other carb brands. I actually have their parts book.

Sounds like it'll be a help on my truck.

It would make a nice slant carb. I think the seller can get kits. "The only thing to do for triumph of evil is for good men to do nothing" "NUNQUAM NON PARATUS!"

But when they went south there was no fix for them. No kits available for them. Clean it, if it's Dirty. Oil it, if it Squeaks. But: Don't fix it, if it Works!
