I was just about to say the same thing. As spud says if it fits in the bore it should fit the piston.

Did you check the piston ring end gap? They can wear fairly quickly which affects tick over. If you strip a machine down to the piston and cylinder its nearly always worth replacing the piston rings as they are fairly cheap.

I presume that there are stihl dealers in Bulgaria, if so I dont see why they cant get hold of mtronic spare parts. I dont know if we ship to Bulgaria but you could add an item to your cart then input your address to get a shipping price. If we dont ship there then as Spud said l&s may ship, someone will.

Its a fuel tank vent. Its a one way valve to allow air into the tank but not allow fuel out.

The sensor usually shuts the engine down if it gets a low reading. A gauge would be handy to keep an eye on things but if the oil pressure all of a sudden drops then the engine needs to be shut down ASAP.

Just a quick bump as it is only running until midnight tonight.

That will be an issue for screwfix. Ive had many a shop customer say that they buy machines from screwfix or B&Q, use them until they are broken then go back and get a full refund. I dont think it will cause us the same kind of issue and at least they can take any "faulty" machines back to screwfix so I cant see it being a problem for us.

Ive never seen a piston with that type of damage before. As suggested it looks like a plug fault/ timing issue due to the damage on the crown and intake side of the piston. Any chance something has broken away and been sucked into the engine?

Mixed feedback on the 2 in 1, some people love them and some hate them. It doesnt look like you have a Stihl chain, apologise if it is, but I know that they dont work so well on other branded chains from customer feedback which is that they take the rakers down too much. I have never used one myself so im not sure if too much downward pressure would cause the issue but I imagine that it would. The other thing that has just occurred to me is that if the chain needs a good grind back then once the first tooth is taken back quite a bit it may be lowering the flat file a bit too much while sharpening the second tooth. If that makes any sense.

As ADW says it could be a mismatch. Post a pic of the worm wheel showing a top down view and the drum showing the part that locates into the worm wheel.

They arent that bad. My customer has basically done nothing to the machine but fuel it up for the last 3/4 years, so its not that bad considering. The cost of some parts has risen to silly levels so if you neglect a machine it can soon start to add up. Machines these days do need a bit more TLC but an air filter, tank clean and a general making sure all bolts and nuts are tight makes a huge difference.
