Hello evening crowd. So I posted a few days ago about an MS660 that I have at work that people were complaining about. The report was that when it was turned sideways it would die. From your responses my game plan would be do the checks that we all know and love: fuel filter, lines, carb, etc. And if that didn't help then I would look into replacing the seals.
So today I had some time to work on it and figured the first order of business was to get it started and go from there. And you guessed it: couldn't get it to start. Now comes the funky part. I noticed a black fluid all over the front of the saw. I quickly realized that a substantial amount of black ooze (that was mostly gas?) was coming out of the muffler! The more I pulled the starter rope the more black oozed out the muffler. So I pulled the muffler off and checked out the piston and cylinder. A nice ring of black ooze around the cylinder above the piston. I also noticed something peculiar: as I moved the piston up when it passed the exhaust port it would start bubbling and fizzing around the rings.
So what the hell is going on with this saw?
