It's funny that people say go with Jiffy................. same motors on Jiffy or Strikemasters.
Bought a bottle of Strikemaster 2-cycle oil and mixed it with fresh 91 octane......smokes a lot less now.
Yes, only 1 screw to adjust on this carb.
Took it completely apart today again, blew out all the ports, made sure everything was clean, put it all back together. Found a small crack on the plastic fuel inlet, so I have some glue on it to seal it up.
Going to double check the spark plug gap tomorrow.
Hopefully after all this, it will run better then it has been.
