" Then about the mid 70s, some people decided that they could do a better job of keeping fresh gas in the secondary side of the carb bowls by adding a secondary idle system THAT YOU COULD ADJUST. MORE OF A MARKETING DEAL VS ANYTHING ELSE.
The open plenum and divided intake manifolds still worked fine with the 2 corner idle system. Dual metering blocks vs a metering plate where you could screw with the settings externally and really foul things up." Good info Tom as always, however, I seriously doubt that this applies to anyone on here reading this. If you can get thru an entire tank of fuel driving one of these cars without at least one full throttle blast I'd like to hear about it!.........

I always find it amazing how much fuel a car uses making a quarter mile pass.

Not for nothing but I've been in the hobby coming up on 50 years and have owned close to a dozen pretty fast older cars, and can't remmeber ever making it thru a tank of fuel without trying to knock the rear tires off them at least once or twice!......

and jetting right the dyno people, said "This carb is perfect don't touch anything". So the engine in your application did not need the 4 corner idle "marketing mods" to make very good power on the dyno. And the tuning was done over the phone. Tom V.
