<VV> Spark Delay Valve - yay or nay?

[Steven]

I noticed a little valve in the vacuum advance hose on my 140PG car which I 
learned is a spark delay valve (SDV), installed on cars with A.I.R. polution 
control systems.  My car had the A.I.R. system removed long ago by P.O.  I 
tested the valve and I believe it is blocked.  I removed the SDV and the car 
ran fine, or so it seems.  Given that there's no A.I.R. system, it doesn't 
seem like a necessary item.  Is there any reason to have one of these 
critters installed on a 140PG that has had the A.I.R. System removed?  If 
not, I won't bother to get a replacement.

Thanks,

- Steve
