    Exclamation Gp 1200 problems

    My gp 1200 has trouble starting and will only start with some help, it has sat for some time. when i do get it to start it will only run with the choke on half way or more. i tryed it on the lake and it wont go to full potential and i checked the cylinders and the the front one is fouled and the other two are burning clean. Could this have something to do with the airbox?
    I checked the compression and its the same for all the cylinders.

    Remove choke plates and put primer kits in Rebuilt carb while you are there.

    the old gas sitting in the carbs has fouled them up the low speed jets are probally plugged clean out the carbs and rebuild.
