Generally speaking, removing the vacuum hose from the regulator will increase fuel pressure @10psi. Pull the hose and plug it with your finger. Note the change in rpm. Increase means your running lean. Decrease would indicate mixture was already close to correct. Leaving the vacuum line disconnected during this test will speed up the engine. More fuel. More air.
I’m still interested to see the results of this test and maybe check the manifold vacuum balance.

I got rid of my alluminum wings and picked up a Goldwing. Here to be a Light.
