Soooo O- 360 , MA 4-5 carb ,dual p mags. Some time ago I was taxiing out and turned Facet electric pump on and realized the engine started to stumble and turned pump off. I only use pump when I notice low fuel press.
During a touch and go I had turned pump on for 0.5 press. I forgot to turn off once press came up and on the roll out waiting to stabilize the engine died. Rut Roh.
I remembered the situation of low power from before and turned pump off used a flooded engine start procedure ( mixture cutoff) and engine fired back up.
Next day I did some testing. Cold engine pump on 4.0 psi. Start procedure, engine won’t start. Turn pump off. Start procedure, engine starts. While engine running at idle , turn pump on, engine dies.... Flooded engine start procedure, engine starts. Run to 1000 RPM , pump on engine runs.
So, engine seems to flood at low power setting or no power ( starting) with the Facet pump on.
Engine/ Carb experts. What say you. Thanks
