Al, does the  p100  exhaust port have a groove machined in the roof of the port.  If I remember correctly the cylinder I worked on for Bob had that feature. Seemed like the saw designers wanted more exhaust duration without the drawbacks.  The slot/groove started dumping exhaust early without loosing all cylinder pressure
