You have a primary or secondary compression problem.

Little trick here
A 1 second spray of carb cleaner own the throat of the carb is flooding the engine so you need to crank it several time with a wide open throttle in order to get a combustable air: fuel ratio in the cylinder
The amount some brain dead egos use on You Bube is almost enough to hydro lock the engine
Warming the plug with a hot air gun till it is too hot to hold in a bare hand also helps to get recalcitrent engines to run for long enough to properly adjust the carb.
Just done a 122LD back from another shop as being "unable to be repaired"
Had to back out the throttle stop 11 full turns which sort of explains why it would not start .

Once a two cycle flooded so bad that it is coming out of the muffler the engine must be cleared of the excess fuel. This done by removing the fuel mix and cranking until it run on the fuel in the crankcase.
But before doing this remove the muffler and check the piston and cylinder for scoring. If scored it is probably toast compression wise and no matter what you do short of replacing the PNC will not help.

If a 2 stroke is flooded the easiest way to clear it is to remove the spark plug and turn the unit so the top of the cylinder is facing down and pull the cord about a dizen times. Gravity will help clear fuel from the crankcase.
