If the carb needle and seat are leaking fuel while sitting the engine might be loaded up when you first start up but three minutes is kinda excessive.
I would lean toward a engine warm up situation verses a fuel clear up change.
I would check valve adjustment and compression.
As far as the backfire, make sure your carb throttle plate is closing completely in the carb throat and not just against the idle stop screw.
Was the OEM soaked in carb cleaner and then washed/blown out or just blown out?
Very important to get all varnish out of it.
