If it's "odd" you're looking for, you've come to the right place...

If your ZS carb has the adjustable needle, set it so that the needle 'base'
is flush with the bottom of the air piston. [Fully clockwise until a
resistance is felt = full rich, fully lean (where the needle holder falls
out of the air piston) is about 5 1/2 turns CCW from there.]

What type of choke do you have? (manual or water-actuated) If the choke
is allowing too much gas into the carb you will see it from a bore
(drilling) just inboard and to the rear of the air piston.
If you continue to have too much gas in the combustion chambers (it _IS_
fresh gas I hope, not the stuff that's been in the tank for years)
double-check the float level and needle cleanliness.
PS is the air cleaner installed? If so verify that you got the gaskets
right way 'round! (Can't cover up the port for the top of the diaphragm.)
Good luck, let us know how you progress.
