<VV> Yenko Carbs Questions?

[Paul Fox]

 Grant, look underneath. If it has a venturi sleeve epoxied into it over time they will leak. I had one do this. Bent a rod because of it. I don't know any way to fix it other than building s new one.  Paul Fox YS059

 I think using 1960 carbs as secondaries may have been mentioned in How to Hotrod Corvair engines.  The rotated adapters and linkage were offered by Otto Parts, perhaps others, and that setup was acquired by Clark's along with the rest of the Otto catalog.

The primaries seem normal, but the secondary ones are from 1960 and they have a sort of rotator linkage system on them similar to what Clark's sells. Hoping there are some owners on our site who can advise if these might be "stock" and if anything different was done to them back in the day that I should look for. They were painted red at some point in their history. If there is a Yenko site, please let me know.
