Second,  one of my carbs doesnt seem to match the others.  Three of the carbs 
(the  two primaries and the left secondary) have brass looking tubes sticking 
up out  of them (the tubes on the left front secondary are a little different 
shape  and size then those on the primaries), but the right side secondary 
doesnt  have any little brass tubes sticking up out of it at all.  Other then  
that the carbs look the same as near as I can tell....   what does  this tell 
me about the carbs and does it need to be replaced with a matching  unit?  

Any and all advice for my upcoming amateur carb rebuild  would also be very 
much appreciated!  

Thanks!

Ray - Are the tubes sticking out of the lower body of the carb, or are they  
sticking out of the tops of the top section of the carb - the part that is  
scewed down onto the lower part. Several models of the H-series have a short  
tube sticking up out of the lower body above the lower vent from the bottom  
chamber. If the tubes are sticking out of the upper portion of the carb, someone  
has started improving the turn cut-out resistance by raising the air vent of 
the  float chamber. I refer you to "How to Hot Rod Corvair Engines" for the 
method.  This is the first step toward providing"enough - but not too much" fuel 
during  faster cornering. Without the increased vent height, if the float 
levels are set  high enough to provide "enough" fuel in the chamber around the 
jet, it will be  "too high" and may spill over (out of the vents) into the 
venturi area and into  the motor. The tubes are the first step to remedy that 
problem. - Seth  Emerson
