Filled it up with gas and oil. Cold 60 degrees and it started. It was running great (30 minutes)then the chain came off. I could hear a noise sounding like water on a hot stove burner.Hissing. I first thought it was the clutch just spinning but it lasted several minutes. I fixed the chain now it will turn over with force about one piston turn. . (vapor Lock perhaps) I took out the sparkplug and pulled it several times. Pulls easy but the vapor lock returns when I put it back in. Someone said to take a Dremel tool and cut slits in the muffler. Any thoughts.
