Drive on a flat road and slowly increase your speed, start at 1500 and roll there, then go up to 1750, 2000 and so on. Observe the reading. There should be a point where the numbers drop.

You need to find the point on cruise where the main jets activate. Doing this will allow you to make adjustments to the correct circuit.

One thing that is a total clusterf*ck in most of the newer carbs is the 5 emulsion main wells. Causes a bunch of issues and is a monkey see, monkey do type thing with carb companies/builders. The old holley 3310 metering blocks were SOLID and had 2 emulsions!!! More isn't always better.

WOT looks pretty good to start with.
