Norm no one here will disagree they can be a troublesome carb at times. You have started 3 or 4 threads on the same issue where we have all offered good advice, when are you going to take some of it? You continually bang on about how many carbs you tried and got the same result, think maybe it's not the carb then? They've been fitted to Victa's for over 35years now, the design is pretty solid i'd say.
Yes the poppet is open slightly when the throttle is set to off, it is supposed to be this way, you are cutting the engine off, not starving it. Why would you even been trying to make it run in the off position?
The diaphragm and spring control the poppet yes, this is the governor, why is this stupid? By all means modify your carb to your hearts content, mine work great just as they are.
