There is a puddle of fuel in the manifold under the throttle body, visible when the airflow plate is pushed down and the throttle is opened. The lower housing of the fuel distributor is damp also.
On the adjustment issue, the engine will run only in a very limited range of adjustment, with the screw approx. 30 degrees either lean or rich. When adjusted hot toward the lean side it runs well, but will not start cold in that setting.
