<VV> YH Differences Re: We are blessed

[FrankCB at aol.com]

One major difference between most (maybe all) of  these "other" YH carbs and 
the Corvair version is the absence of a vacuum  advance port on the Corvair 
version.   Since these "other" YH  carbs were used on NON-turbocharged engines, 
they most probably ALL had  vacuum advance ports located in the throttle body 
section of the  carb.  I've examined YH carbs sold at Corvair events and 
occasionally  found a few with vacuum advance ports which indicates they never came 
off a  Corvair.  If you do get one of these for your 150/180 and want to keep 
it  completely stock (and don't care about better gas mileage), be sure to 
plug the  putlet of this port so it doesn't leak air into the carb and intake  
manifold when the throttle is opened above idle.

The  Hudson/Nash variety of the YH is closer to the Corvair (probably its  
predecessor) than the Corvette, with about the only discernable difference  
being the throttle lever and non-chrome parts. The Lemans and Healey versions  
used a matched pair of them (as did several marine Y-Block V8's). Sadly, they  
are bringing a little less than the Corvair version as they are more  plentiful. 
They can be used on a Corvair without anyone being the wiser,  however, if 
you swap the throttle shaft and choke link and grind off the part  numbers and 
paint it black. (If anyone is interested in doing that, I have a  ton of them. 
They are the same size as our 1962 carbs.)
