Thanks for your suggestion. Forgot to mention that my body informed me that ignition was not giving the "click" sound while rotating the prop slowly...
Could this also be an indication of some sort on the difficulty to start this engine??
I own many DA engines from 50cc to the 170cc and never ever had an issue with any of them. in fact I don't Remember ever having to tune any of them or at least having an issue getting the best of them...
