I recently acquired a 60 johnson that starts ok but doesn't idle very well after running for 10 min or so. I think it may to have the carbs cleaned as the fellow I bought it from said he didn't use it for the last 2 years.anyway I ran it in the lake and it started running fine and then I backed it off.The next time I opened it up it did not want to take off and stayed at about 2800rpm. I backed it off again and then off it went. The buzzer never sounded and it does chirp when I turn the key on. I took it home put on the muffs to run some seafoam through it and the head got so hot I couldn't keep my hand on it. I removed the tstat and then the head stayed cool but the telltale quit working. I am not sure if it quit because I took all the back pressure off?
what should be my next step?
Is this tsat supposed to look like a little rocket as I have never seen one like it?
Is the lower unit easy to remove on this model?
thaks for now
