Carb question

Post by 1969zeitler »

Which is used by most Vintage racers 28 PIC or 28 PICT? Are they both legal for Vintage? Does the universal rebuild kit cover both carbs? Thanks. Roger

Most everyone uses the 28PCI. The rules allow the venturi to be replaced in most venues. You can replace the 28pci venturi and increase flow by 30%. The 28pict has a fixed venturi, so you don't see many people use it, allthough it would be legal.

I THINK the rebuild kit works with either carb, but I have never even tried to rebuild a 28pict.

The rebuild kit for a 28 PCI will NOT work on a 28 PICT. The accelerator pump diaphragms are different sizes as are the gaskets for the top cover. Jim is correct about the venturi diameter. If you wanted to go to the trouble, you couldn't bore out a 28 PICT to be as large as the 28 PCI due to the size of the casting. In case anyone wants some 28 PICTs, I have some that I'd be happy to sell for a great price....

Checking thru my boxes of parts I found 2 28 PICT carbs. I guess they will work until I can find a PCI. Do any of our suppliers carry the larger Venturi for the PCI carb? Thanks

Roger:

I would guess that most of the suppliers have the parts you need- including carbs.

The 28 pci's can still be found on e-bay or thesamba. (but they will need to be modified and rebuilt)

Yes, We have the carbs, venturis (or most any carb part you need.)
