Having blunted off a chain cutting a stump, in putting the sharpened chain back on I realised that I hadn't checked the clutch in a while. Block cylinder, LH thread and off it comes. Bell was quite oily, as was the clutch. Removed worm drive - a slight bit of lead in thread missing and a few tiny pieces of plastic. Turns easily and oil is being used at the correct rate.
50Nm to re-torque, except my wrench isn't left handed.
Fuel cap was leaking which turned out to be grot in the fuel tank on the seal. Emptied and cleaned tank and replaced fuel filter.
The air filter was changed too, which largely stopped the stalling it does when started hot.
