I just bought a glastron mx 185 with a 3.0l mercruiser tks (carburetor) I hooked up ear mufflers and turned on the water hose and it fired up, I then shut engine off 1 or 2 minutes later after running and tried to restart it but it would turn over at all... it didnt even try to turn over there was nothing at all. I waited about one hour before trying again and it started. I did the same process a few hours later and it did the same thing, it started and then wouldn't after shutting it off and trying again.... thanks for all the help in advance
