Stihl km90 suddenly won’t fire

[HDAV]

Thanks I left it with the old man to sort of they can’t sort it I’ll get it off him and strip it myself I did the valve check when I bought it it (it’s a well used older model) and it’s been running great for over a year a bit circumstances have meant I’ve not been back to see my folks so often the last 18 months or so 🙈🙈🙈

If it still plays up, check the tappets and also the gauze strainer, just done two more of these. One seemed to have low compression and the tappets were a bit tight. Backing them off restored the compression. The gauze strainers were also a bit grotty - remember to flush the tank out if you find chip in the strainer.

Hope it is sorted though!
