One other comment on the Rear Power Valve.
You can buy the Rear Metering Block Power Valve Plug (and think that you are good to go) but the reality is you will also have "cross-talk" between the two Metering Block Main Wells at high jet flows.
So if the Metering Block has a provision for a Power Valve the common remedy to also add Power Valve Channel Restrictions.

On a boosted carb you can tune extra fuel flow with these restrictions and on a NA Carb you can also, if you want, put in blank plugs (thereby removing the main well "cross-talk" and then add the Power Valve Plug. It is the little mods that many people miss in the Carb Magazine Articles that can make a difference.

(You want the Main Jet for one Booster to get the true signal from that Booster, not the average of two Boosters at high fuel flows.)
