I went to use the saw to do some cutting ( was at some guys house scrounging some oak). I started to pour the gas in the saw then decided that it would be a good idea to shake the can to mix the oil,after I shaking I poured the gas in the saw I noticed it did not look right. The saw ran for a few minutes them died and would not start. When I got home I poured the gas into a glass jar and this is what I saw. The last pic is the new gas. Pretty sure some DB took half of the gas and filled the can back up with water. I bought a new can of Trufuel from Loews ( I poured some in a jar to check that is was OK.) I emptied all of the bad gas and put in the new gas. The I got the saw started and after running for a few minutes the saw cleaned up and ran OK. I guess Trufuel needs a tamper proof seal.
