Gay's right, I run just under 3 psi and it works fine. If it goes over 3, I start to have troubles.

I never had trouble with Weber's that were provided with 3 psi. However, if I WAS experiencing flooding issues at 3 psi, I would not hesitate to try 2.5, then even 2.0 psi to eliminate the problem.

Then again it all comes down to how accurate your pressure guage is.
