well it least it runs not bad on the pipe , like I said its lower on rpms on a gas motor compared to a alcohol motor but that pipe sounds to be pretty good on the 2159 , donot worry about matching the ext. port to the pipe as its the other way , the pipe inlet is bigger than the 2159 ext port outlet , your not going to gain hardly anything matching the pipe to the port, advancing the flywheel abit will make a bigger gain

there are always gains to be had but as far as big gains , the flywheel would be first, carb would be next and stuff like the squish , that saw is working well in your air so I would not do much to the porting cause most likely you will loose power, what works in 99% of the country does not work in your area on porting numbers

Saw has the small spline drum, have to get the standard center drum before I can try an 8. If it gets any colder I am going to pull the pipe and use the saw for firewood.
