OK, here's what I have to work with, it's as near as I can tell a Holley 800 CFM DP. Carb numbers are LIST-4780 3532. So far I've not taken it apart. What I have noticed that's screwed up is the Primary Fuel bowl float adjustment threads in the bowl are stripped, the metering blocks appear to be missing the idle adjustment screws and the squirters look too new for the carb. I'm not even sure this came with the OEM metering blocks. It has the 30CC primary pump and the 50CC secondary pump. It looks like the pump cams are missing from the throttle shafts along with the screws. I'd like to get this thing back to square one and working before I start "working on it." It's been 15-20 years ago when I was using a Holley, I can still work ona Q-jet blind folded. It is my intentions to go against a lot of you guys suggestions and build a blow-through carb myself. What pump cams and part numbers do I need to order, as well as the adle screws? I looked at the Holley site and it just had a generic picture diagram of the thing. I'm open for suggestions. I have more time than money right now. I do remeber from the past that at some point you can get to where you can take the metering jets out and throw them away if you have the wrong meteringblocks because the fuel apssages are too small. I'm sure when I get my feet wet again it'll all start coming back to to me, so refresh my memory if you would. I like used parts better than new, so if you have some "junk" laying around I'm open for offers. I plan to follow the http://www.hangar18fabrication.com/blowthru.html to build my carb once I get it back to square one. Thanks, Floyd.
