You are showing what is probably a really oldschool 2 stroke, yes the principle is the same to date, but additions like
Reed Valve induction (preventing carburettor backwash)
Exhaust rotary powervalve
All of the above working in harmony provide a very powerful output - the problem with the output is its very snappy, like a snake attacking as compared to a 4 stroke where the power is tractable - like a very big horse - slow but steady
the 2 stoke would be like - very hard to handle.
POWAAAAAAAAAAAAH (banshee scream)
