What are people's strategies for cleaning muck from the saw near the base of the cylinder before removing the cylinder?

 

Obviously an air gun, but do people degrease or anything? I've been working on a few small saws recently where access is limited and have been considering this issue sine an airline doesn't budge enough stuff really....

Bit of white spirit/WD40/GT85 etc, work it in with a paintprush where possible and then use an air gun on it. Removing the muffler and doing it from the front and back and then the flywheel side tends to get a lot out.

 

Just make sure the crankcase cavity is plugged with paper roll after the cylinder is off, I HATE it when kit comes in with this not done. A bit of woodchip in the main bearing can knock them out if not cleared!!!

Was asked to take a look at this husky 135 as the chain brake wasn't working, its not very old and seen little use, I took it apart thinking the band had snapped but instead found this. The three plastic studs on the handle have worn and the metal brake linkage skips over instead of being engaged.

is it just a poor design, heavy handed use of the lever, or something else?

Probably been caused by the side cover being removed with the chain brake still being on and then having to push the side cover on to the brake handle to take the brake off and it slipping.

 

If the side cover is fitted correctly, the mesh should be deep with no chance for this sort of damage.
