Hi guys,
I'm attempting my first carb rebuild for my 98 four winns with a 4.3 volvo. It has a holley 2 bbl 2300 series carb with the list number R-75006A. I bought what I thought was the correct "Renew Kit" (Holley 37-474) only to find out that it has a different accelerator pump diaphragm (i think it is a 50cc instead of 30), a different power valve, a different metering block gasket and also a different needle valve and seat. I have checked Jegs, Summit, and Holley's websites and cannot find any reference to this carb. Can anyone tell me what part number I need for the renew kit. I have the carb in pieces, cleaned, and ready to assemble, I just cant find the parts. Any help is greatly appreciated.
Thanks,
Jimmy

Thanks Brian,
I think I have determined that the gaskets I got with my kit will work, Im not sure about all the small o rings though. I found the 2.5 power valve required at Advance (part 125-25). However, I'm not sure which diaphragm I need. Best I can tell I need a 30cc diaphragm and from the photos on summit's site it appears to be 135-10. Can anyone confirm these part numbers? Brian, where did you get a hold of all the small o rings for idle screws etc? Thanks, Jimmy

Here is another thread about someone asking about a Holley 75006 carb that I found:

http://forums.iboats.com/showthread.php?t=525854

Hopefully you have more luck than me. I have a 75034 carb (also a 2bbl 2300) and Holley said it was a "proprietary Volvo Penta carb" so they do not carry rebuild kits for it. If all else fails, I bet Volvo will sell you a rebuild kit which will have their part number on it and cost more than it should.

I saw that thread before I posted my question but it wasn't much help. I didn't even think about checking for a volvo part number for a rebuild kit. I went there and found part 3854020 which i just purchased from the iboats store for 38 shipped. Thanks for your help.
