<VV> Single Carburetor

[jimster1]

Of course, nothing kills low end torque like a too big carb......or a cam
too "hot".

You are out of standard answers here. Once you modify, you start the
learning curve. Two HVs are really simple to use. 

First, fix the vacuum problem of the vacuum advance going the wrong way.

Might need to research a small block Chevy to get the vacuum diagram as to
where the hose ports are you need to use. 

The distributor on a Corvair uses "ported" vacuum, not manifold vacuum.

I have a 65 110 that I have rigged with a single Rochester 2 barrel  
Carb.  Runs fine, idles fine, the problem is the engine doesn't have  
much low end torque, once I'm moving along it is okay but off the  
line I need to keep the revs up.  I think the drop in vacuum from a  
carb that may be too big is throwing off the timing, the distributer  
vacuum retards the timing when I press on the gas to start out.  Does  
anyone have experience with these single carb applications?  any ideas?

Thank you,
John I.
