The bit of the tension screw that engages the bar on an old stihl I'm fixing is badly worn and I haven't got the new part yet. And when I ran it the chain became loose very quickly.
I wondered though should I expect the new screw to fix the issue, or once it's tensioned and the bar nuts are tightened down should it not hold tension regardless of the screw's condition?
