When you put carb kits in you either did not put needle valve spring in or you changed spring out to a lower tension spring if you dont know how to perform a proper pop off test then you need to take somewhere to get it done. They have to pop off at 20 lbs. Pressure and there is a special tool to perform this test. When the engine is shutoff the fuel tank builds about 2.5 lbs of pressure because it is a plastic tank and that pressure gets forced through fuel lines if you dont have proper spring tension it will go through carbs and fill cylinders a temporary fix is to simply shut off the fuel valve when your done using it
