Stihl 025

[iaing]

I have just got my 025 back from the shop.
They said (like the last place) it was fine and ran for them for 20 mins.
I can get it to start 50% of the time but then it dies and will not restart. It will not run 20 mins.
Any tips / ideas would be gratefully received.
Thanks.

Sounds like coil shortin out. or clutch side crank seal bad. run it and when it dies see if it has spark ? if it has good spark its possible the crank seal is expanding when it heats up and not sealing .
