<VV> Performance carb questions

[Bryan Blackwell]

Hi Brad,

I think some of the answer depends on how much the secondaries were  
bored, and how much difference in size there is between the venturi  
and throttle plate.  For a stockish 140, 51s seem to be a good  
starting point.  With the relocated jets you won't have the high  
speed enrichment which is worth a couple of jet sizes, so maybe start  
with a 53 or 54 in the primaries.  The secondaries may need something  
really big, like a 60 or so, depending on how much signal you're  
getting.  If you can let us know where you're at now, and how the  
plugs look, that may help.  Don't forget that too big is also bad, so  
if the jets are huge and the plugs are black, you may need to go down  
in size.  Good luck.

--Bryan
