Chainsaw Repair

Thank-you gentlemen 'all. That is why I am here to get into the real nitty gritties.

Saws have been a large part of life. Logger, feller, forestry/chainsaw/clearing saw instructor, silviculturist/chainsaw/power carver.
First pulled the saw'stinger in 1969 when a 'wee power'saw kid.

Owned 60 to 70 saws over the course of a long career in the wild, deep woods. Operated, loved and cursed most major brands, European, Asian, American and even Canadian... 'eh 
Learned to fix most... a lot of them on the fly, in the bush on a log, pulp pile or a snow bank.

This 281 is a trade, swapped out, in exchange for a little Stihl I fixed up, we were both happy.

Came to the point with the gas leaking out through that bad tank grommet seal, and as the fuel hose deteriorated and ripped, she finally quit. Used sporadically over three years, so 'hey it was expected... needed rear mounts anyway, so decided to upgrade and throw in what I could.

Yep, the impulse was considered, still is, and with renewed vigour as the feedback comes in. The original gasket to the head was ripped, so at this point with each tear down of the carb, have made, three gaskets from good gasket paper, hoping the last one pictured here is sealing properly, quite sure it is. Making sure the impulse hole is drilled out too, aligned with hole in head.

Oh yeah, the new gasket to the insulator has a hole in it, does it align to the factory hole? picture included.

Pried off the oiler/seal plate and as you can see pretty much plugged up.

The O-ring, not pictured does look ragged, not sure about the seal. Putting a picture up.

The expert info from you guys is a help indeed. Some good investigative tips... 'fer sure.
