I have a small chiansaw which has an Italian made "Pini" 32cc 2 stroke engine.
It is supposed to have "easy start" and used to start 1st time, but now takes quite a few cord pulls, with full choke to start only when cold. Once hot, it satrts no problem.I have replaced the plug, but no change. Could it be the Oil/fuel mix screw, as I have tinkered with that recently ? I seem to be getting a reasonable spark.
