I'll have to try flushing it. I have a sonicator here, so if I can find the removal tool I take it off and flush it out. WD-40 flushing will have to wait until it gets a little warmer (Wind chills are in the range of -5°F!)
If that doesn't work, I'll deal with it later.
Worn cogs are not random, the chain will jump like clock work....
Very cold temperatures will affect pawl perforfance as the internal lubricants (or lack thereof) lose viscosity....
You can flush it on the wheel, lean the wheel at an angle, stuff a rag or paper towels between it and the spokes and flush away. The rag will soak up everything coming out of the back.
