Torx key ordered, thank you Spudulike 🙂

 

I also saw you recommending doing the rubber swap dance when starting with MotoMix which is what I plan to do for any saw(s) I get since I’m a “very occasional” user. 
 

Even if this saw ends up in bits on the floor I’m going to try to soak up all the knowledge I can do thanks all for your help 🥳👏😇

I've just checked mine and it's a 'B'.  My piston is good, my cylinder is not, it has a stripped thread at the spark plug.  I was thinking if your cylinder is saveable we could marry it up with my piston but not so sure now.

Easier to fit a helicoil than to dissolve off aluminium pick up and de glaze a bore with wet and dry.

 

Remind me of your rough location?

Can't though, someone has already, very badly and plug won't seal now as the top of the port, the surface for the plug to seal against, is chewed up.  That's the annoying problem

Timeserts have a flange that the plug can seat on but I haven't used them.

I know, I think they might be worth a try but I don't know anyone with the proper kit and I'm not buying the kit for one insert, it's not worth it.  Given that it's been tapped for a helicoil I fear there may be a lack of material for a timecert
