Actually, there are lots of adjustments for that, main jets, idle jets, idle screw, needle height, needle shape, slide shape, float height, etc. etc., never mind.
When you say you have cleaned the carb have you manually cleaned the jets? That would be my best guess. Otherwise, is the float at the correct height? If it was me and I was convinced everything was perfect fuel
mixture wise I would go one range hotter on the spark plug
but I do NOT recommend that to anyone who does not understand that the wrong heat range can destroy your engine
Of course you could always run it WFO for a minute or two before going into the dinghy
