Hi
I have an ms270 on bench.The saw came to me with the complaint that is not running good.I pressure tested it and found an air leak at the cylinder sealant so opened it and replaced the sealant, the crank seals,the bearing and the piston rings.The piston is in very good shape.I am trying to fire it up with no luck.Replaced the ignition coil with a brand new.Swaped the carb with a known working.Pressure tested again with no leaks.The chainsaw doesn't want to start.Today i did a compression testing and read 122psi but the cylinder and piston is in very good shape.I don't know what else to do.
