i bought an olympyk 970 echo cs5000 and a husqvarna 36 today for 50 bucks the echo and husky run i cant get the olympyk to fire its sparking what should the compression on this be and it also pushe fuel out the fuel line when you unhook the carb even after i drained the tank it pushed what was left in the lines out like its pressurerized is that normal on these saws?

piston is toast,but it still had 100 pounds compression.still wondering if that fuel pressure is normal
