<VV> Carbs

[BBRT]

OK Folks, From the Tech Guide, in the "Rochester 'H' Identification" article 
by Larry Claypool, where he addresses this issue.

"Since all 1968 & 1969 models were factory equipped with smog pumps, these 
models used the previous California-only carburetors - that is, primary 
units that had the air bleed and no power enrichment. A new feature for the 
secondaries was a "fixed fuel feed". Essentially, this was a non-adjustable 
idle circuit. The new secondaries could now use some of the fuel in their 
bowls even if the driver never opened the throttle far enough to use them. 
This went a long way in preventing stuck or clogged secondaries that are 
typcial of overly "slow" drivers."

Richard, perhaps you can modify yours or exchange them with someone like 
Grant Young who does carbs and probably has some of the later secondaries. 
Having suggested that, if you are using ethanol fuel, it is going to be 
difficult to prevent carbs from gumming up.
