I would remove the air filter and look at the choke lever inside carb. with motor cold it should be closed. the rod runs from the carb to muffler and as motor heats up it releases the choke butterfly inside carb. There are a common issue. It could be just a dirty carb or ethanol problem also, but I would check to make sure choke is opening and closing properly first. you can also attempt to drain the carb bowl and then try to restart before pulling entire carb. sometimes pressure release on float will fix any clogging issues on the needle and seat.
