fuel dripping from primary booster nozzles

I have a sbc 350 on a test stand. It has an Edelbrock 1405 carb. My fuel pressure gauge shows between 7-8 psi and I know Edelbrock recommends 6 psi max. When the motor is running at cruise type RPM (say 2000) I see fuel dripping from the primary boosters. Not sure if that's correct or not.

That would be more than less correct. The fuzzy answer goes back to a bit too much fuel pressure and running on a test stand where there's no load on the motor so getting 2000 RPM shouldn't need much throttle opening. But the fuel "drip" is consistent with enough air flow to cause the boosters to start feeding. They would come on early if the fuel level in the bowl was higher than necessary, but at this point I wouldn't worry it till the engine is installed in something and you can put some load on it to see how it's working.
