<VV> Carb mystery

[FrankDuVal]

Bending linkages on carburetors is normal for many brands. Choke links, 
accelerator links, etc.

I have no idea why you think the idle vent valve is egregious. It just 
vents the float bowl to atmosphere (not through the air cleaner) at idle 
to eliminate the hot percolation problem.  Real simple solution to a 
problem. The Rochester HV is NOT the only carburetor to have an idle 
vent valve function. And BTW, you bend the tang to adjust.

Remember, our cars need to survive (let me recalculate for you ) -20° C 
to 50° C and from less than sea level (-100 feet, [-200 in Death 
Valley]) to 10,000+ (Pike's Peak is 14,000!) feet in operation off the 
showroom floor for hundreds of miles at a time.
