    Check if the carb gaskets are in good condition and if the fuel lines are intact, no holes or cracks where air may seep through. Air in fuel will, at times, cause stall at high rpm.

    Check for cracks in fittings and carb body pieces too. These can stay closed at idle, yet open enough to admit air once some heat gets into it.

    Well I may have found the problem. The new fitting from bass pro shop for the fuel line is super loose where it meets the engine . Put the old one on and seams a lot better .. Gonna try it this weekend and see what happens :D
