Chainsaw Repair

It seems you are having a high rate of failure though.  It is a misconception that these new saws are set/ready to roll out of the box(not saying you fall into this category).  There has been many instances of the metering lever being way to low, causing the saw to accelerate poorly and start hard warm and hot.  Also the pop off pressure is for some reason very high.  I clipped one ring off my 562 and it starts well at any temp.

Why the 100 fuel?  Just curious.   My 562 handles the transition from 87 to 92 flawlessly but vice versa, it takes a tank to adjust.
