this is a saw from work that has an issue,it was taken to the stihl dealer and was diagnosed with poor compression. damn thing wont rev out has no power.so I took it home and put the gauge on it,i get 75 psi with a dry cylinder and almost 100 psi when I oil it up.removed the spark arrestor and it was nice and clean,checked the spark at the plug and it was weak and intermitant.just wanted to confir with you guys before I order a new $152.00 ignition module. im not sure what the psi should be but it seems good to me.what should I try next???
thanks
