i used to do a lot of 2 stroke honda moped repair, rebuild, hop up etc..
iron cast cylinder with aluminum piston
remove the exhaust, soak in safety solvent, blow out in reverse with compressed air (air in the tail pipe)
but back on the engine and let it run until all the smoke is gone
when first started it will smoke like a fog machine
great way to kill backyard mosquitoes
amisol or other synthetic 2 stroke oil, leaves NO carbon in the cylinder or exhaust
over oiling with cheap oil clogs up everything with carbon
since it is hard to start, even with starting fluid
there are two possible problems
sticky reed valves from fuel varnish
and carbon in the head which absorbs what little fuel is getting through
all depends on how hours of run time, low hours is probably sticky reed valves
lots of hours could be carbon or both
