I believe it is siphoning gas through the primer and flooding the machine.when it is cold I have to primer it to keep it running but when it warms I have to unplug the primer or it will flood.i replaced the primer but the problem still persistes.i installed a gas shut off on the main line.to start it, I need to shut off the main fuel line, primer it till it starts,then turn on the fuel supply and unplug the primer when it warmes up so it doesn't flood. after all tht it seem to run good.but if I don't shut off the fuel line and unplug the primer when I shut it off it will be flooded when I go to start it again. any suggestions?
