Chainsaw Repair

On the issue of how this happened to the saw.  I was randomly looking around the forum and found thois by KRL.."..If there is no mix oil left in the can after the gas evaporates off then chances are that the saw was fed improper fuel..".  I then realized that this was one thing I could have done.  Not to assume that the gas in the tank was the same gas as when it was damaged,  but if the gas was low on oil or without oil then that is a probable cause.

Without thinking through any such things,  on buying the saw I washed the gas tank and tried to start it with good fresh fuel.  I think I will never buy another saw without pulling the mufler first.
