The engine was coughing/spitting very obviously. Since I put in the new used carb (bought from E-bay for $40 since it looks very good Johnson OMC Evinrude Carburetor for 1973 20 Hp 385814 Removed from a freshwater 1973 Johnson 20HP Model 20R73A). The used carb came from the same my model number. The old carb was in not good shape cosmetically. It was hard start with the old carb so I try to get a new used one to see if the condition improved. Attachment are the picture of the new used Carb. But after I took the video of the motor running. I stopped the motor and I could not ever start it again even though after many pulls and adjusted the idle needle. The Carb had been cleaned before installed on the motor.
