Put the high speed carb knob around 6 or 7, and hold the spring-loaded choke down with your left thumb as you pull the starter rope with your right hand. If necessary, try the throttle between start and fast and all the way up on fast. The exact carb adjustment doesn’t matter much for getting it started because the choke is pulling it way richer anyway, but if the high speed carb needle is too lean the choke can’t get it to suck enough gas to start it. Some of these have a small brass screw horizontal at the bottom center of the carb bowl. That is a carb drain. Back the screw out and see if clean gas drains out.

Check the simple stuff first – maybe the spark plug got wet or fouled.
