Chainsaw Repair

 Poulan doesn't say what max rpm is in the service manual or owners manual.
Initial adjustment of high- and lowspeed mixture needles is one turn open
from a lightly seated position. Make final adjustment with engine running
at operating temperature. Adjust low- speed mixture needle  so engine will accelerate without hesitation.
Adjust high-speed mixture needle to obtain optimum full throttle
performance under cutting load. Do not operate saw with high speed mixture
setting too lean (needle turned too far clockwise as engine damage could result
from lack of lubrication and overheating.
Adjust idle speed screw so engine idles just below clutch engagement speed.
