MS211c weird problem

[spudulike]

Build up of oil from the fuel mix around the rings and bore...got to be and bet now it has run up and burnt the oil off, it is easier to pull over! 

Glad you got there in the end though!

Ah, but but but! Having dismantled it, checked rings were free, cleaned pot with w&d and WD40 and then given it a good scrub in hot soapy water, I'm inclined to think it responded to some selected language this morning....

Did you clean out the ring grooves with solvent or just check rings moved in grooves ? 

 

The fact that the saw ran at all tells us there wasn't a mega amount of friction. If it idles on std carb settings (ie carb idle speed screw not wound in), that says the small amount of combustion energy is enough to overcome the normal engine friction at idle. Any extra friction in the engine is most notable at idle where the combustion energy is tiny.

 

Does it pull over noticably easier now ?

Started this morning again, ok but a little tight for a little saw. Anyway, runs up fine and tick over a treat now. Advertised today. I need to sell some saws as I am overrun with small ones.....
