<VV> Single Carburetor

[jvhroberts at aol.com]

 There's a reason why Chevy didn't try this, even though VW did. VWs had lower specific output engines, and all that runner length, if one were to maintain velocity, is restrictive and tends to 'demix' the air/fuel mixture. 

Generally, the vac advance goes to full retard when you lose vacuum. 

I hate to be the one to say it, since you clearly put some time, money and effort into this, but why the single carb over the stock setup, or some variation thereof?

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.
