Having replaced cylinder head gasket on my 1931 Chummy, stripped down and cleaned the Zenith carb, checked ignition etc the engine  seems to be running a little roughly (small adjustments to the ignition make no difference) and the plugs are very sooty indicating that the engine is running too rich. Looking into the cylinders there appears to be small amount of oil/unburnt fuel (not certain what) Understand that it is not possible to adjust the main jet mixture  (apart from changing the jet size). Can any one suggest anything?

Regards
