Does this engine have reed valves in the intake? Perhaps the reeds are worn out and you arent getting decent inlet charging?
You should check the engines compression out with a screw in gauge.
It goes in the spark plug hole. They also make ones you hold over the spark plug hole that fit odd sized spark plug holes.
If you arent getting over 80-90 psi after two or three kick starts...you probably need reeds or piston rings.
good luck and be careful!
