Default Re: old dog still not running right

Will it stay running if you keep the throttle partly open? Turn the idle screw in a lot more.
Missing? is it way too rich and firing every other time sounding like a machine gun instead of a purring two stroke?

What color is the plug? White (too lean) Black and oily? (too rich)

How many hours on the engine? is it just worn out to the oint that the compression is too low?
