    mgt 8.0 carb pops out while running

    my mgt 8.0 was converted from a 4.6 a few years ago. Everything was bought new to convert it. 3 times now, the carb has been ejected from the engine while running. I have tightened the pinch bolt and collars in the correct position twice, this last time I tried a fast dry epoxy. That held for about 5 minutes. No damage to the carb neck or the block bore.

    Things I am thinking about trying
    -making a notch in the carb neck and flip the pinch collar so the round side is against the car
    -drill a hole through the case and dent the carb neck, install a set screw (someone told this on another site)
    -install the pinch bolt/collar and jb weld the carb to the block

    what are your thoughts, any ideas?

    RE: mgt 8.0 carb pops out while running

    Perhaps your throttle servo is travelling too far, thus pulling the carb loose,

    try setting the end point on your throttle, to eliminate the servo extending past carb when full open.

    Its me is that you?

    Don't belive servo is that strong! I read this before a few years back and what i believe the problem is the pinch collars are too long they touch before there is a good bind. Try grinding material off each of the collars shorting them just a little. That should do the trick> I will try to find the post
    It is! what it is!
