im strating to break in my new engin (27ccDDM).
and the idle was off so I set it with the idle scew(big one hard to get).
trun it up till engin wouldnt stall.
had to screw it all the way.
then i tough why not try the low needle.I turned idle scew all the way back and set the low speed till i got good idle again.
then i strated think,this could be bad for engin if im runnig to lean.
So the question is where do I put idle scew?middle,back or fully in?
thanks for your help!
