Two 28 pci's.
Which one of these is correct for a '56 oval?
And what is that opening for?

thanks,

The on on the left since it has a screw connection.

I don't know what that opening is for but since the right-hand carb. has a push-on fuel hose connector, it must be much later (late model standard Bug?) or a later replacement carburetor.

Talk to Ed Fall in SLC. He knows everything there is to know about those carbs. Vinztage Werks

For anyone researching this the answer is:

Yes, the port you're pointing out is an additional vacuum port on some of the later carburetor bases, most commonly found on bus and Ghia models though sometimes used on beetles equipped with a different distributor than the normal VJU 4 BR 8 found on most 36hp engines. Either carburetor will work but the one on the left without that port and with the threaded inlet on the carburetor top is the better choice and the correct style for a bug

The one on the right was also used on the "Bastard 40" engine used in the VW Bus.
(Still 36hp but with the new 40hp style design).

Not the best photos but you can see it has a 28PCI here with a rubber fuel line running to a pressed-in inlet:

Note that I am primarily talking about the 28 PCI with a pressed-in fitting.
I cannot speak to whether all or only some Bastard 40 engines had the vacuum pressing.

True!

There are still some others floating around with the vacuum port and regular threaded connection. Always entertaining wading through info to find a part during a good hunt!

Figured I'd resurrect this thread. I just picked up 3 36hp engines and one had a bastard 28PCI with the vacuum ports on both sides. Mine doesn't have just the boss on the left side, it has an actual brass tube, and the threaded area at the base on the right side. I wonder if there would be a difference running wise between the two ports.

If the ports are on either side of the throttle butterfly then the answer would be, yes.

There are some with a threaded fuel inlet connector and the provisions (not drilled) in the casting for a vacuum line on the left side. I don't know exactly when this started, but older 28PCI carbs don't have that. I don't think any of the ovals where that way stock. The replacement 28PCI on my '57 is such a carb.

There are some with a threaded fuel inlet and a vacuum port on the left side. That is either venturi or blended vacuum and was used in the U.S. on 1960 Karmann Ghias. It is the only 36 horse engine we got that used a vacuum only distributor (like the 40 horse, but a different vacuum only distributor.) That setup may have been used in later standard Bugs with the 36 horse sold elsewhere.

That sounds familiar, I think someone mentioned a Ghia or something having a one off type setup that used this carb and a very rare and hard to find distributor.
