    wait for the carb   job results          sounds like fuel flow issue …doesn’t take much to clog a jet  or inlet needles

    have you ever tried a can of  fuel system cleaner  with some fresh fuel …..

    if carbs  were… fine….  check  for proper venting …

    the other possibility  is a heat related  problem affecting a component… try  running with the cowl off
