first question i should've asked. did you flat plate sand the flats on your carb.
if you didn't do that first.
after you are sure its sealed, TRY venting the carb by loosening the screws and letting gas seep out.
i had a flatback i tried everything on till i tried that old chainsaw trick. it went from the most annoying carbs to one of my best.
BUT i ALWAYS have to vent it at beginning of year sometimes several times.
theres some weirdness that gets them airlocked on occasion and that tip fixes the air lock.
also soak the diaphram in tranny oil.
sometimes they come back to useful.
or i think if you double the gasket you can use a newer mcculloch carb diaphram.
