I am having a problem with my 60hp johnson tiller, once I reach operating temp (about 5 mins of running) I start to loose RPM's till motor is running just above trolling speed. I have tries pumping the fuel bulb and pressing the primer/choke button with no change. Any ideas??? Please help

Is it overheating? Use a timing light to check spark on all cylinders to see if you are loosing spark.
Does the spark plugs show any signs of water intrusion? Use a squirt bottle of fuel mixture and squirt fuel into each carb and see if it helps.
