Well if I rotate the cylinder to around TDC I can feel the clicking spot.
Then I wiggle it back and forth a degree or two on that spot it feels like there is a bit of play and it feels rough.
I can't tell if its the crankshaft or the connecting rod causing the click. It certainly doesn't sound right.
I have been running Husqvarna and Dolmar synthetic 2 cycle oil. I bought this motor in January, just after they came out.
It always had a little click to it, now it is very pronounced.
