I installed a new float bowl and reattached the float mechanism in new one.. When started car it spilled gas thru the adjustment screw all over.. Even when car is off but ignition on with electric water pump was just coming up and out like crazy..yes, the bowl is tight on carb... Have I stewed down the float so much that is keeps calling for fuel?? Thanks, new to this work...thanks,, it's a 850 double pumper if it matters...
