I am at the end of what I know to do with this chainsaw. I was given the chainsaw with a new piston to install. the old one was lightly scored. I cleaned up the cylinder and installed the new piston along with new bearings and seals I buttoned it up with permatex put it back together and it ran great. the saw was sold to a firewood guy. we tested in wood and it ran great. 2 weeks later it came back he said it would not idle when started. I tried it and it seemed to have an air leak. the piston that I put in was lightly scored so i took i apart and replaced the piston and jug with an after market ms 310 piston and jug. buttoned everything up and started the saw only to have the same symptoms as before. I rebuilt the carburetor still no good I replaced the pulse line and intake boot still same problem. I took it apart again and tried a different permatex sealent i even put it where the seals cradle in the block. have no more ideas. Any thoughts?
