Strange clanking noise when I use the compression tester on my Husqvarna 257. Almost sounds and feels like the tester valve insert is making contact with the piston head top. Clank, clank, clank as I pull it over. Needless to say I stopped immediately. Doesn't look like it's any further inside than the spark plug would be. Anyone else ever experience this?
