I have received good feedback from the group and wanted to post another problem. I have a 135hp 1989 Black Max. I rebuilt the fuel pump which I thought was the cause of the random stalling. After doing so the problem reoccured. After a bit of playing around with it I discovered that removing the cover allows it to work fine--no stalling out. What would cause this? Also, I pulled the plugs after wards and noticed that there a little wet--not excessive. Could this be a sign the carbs needing rebuilding? I have not done a pressure check as of yet but don't suspect this is a trouble spot as the motor runs strong.
