I've just had a replacement for my Ryobi RCS2040 chainsaw as the motor had failed at less than a year old. Trouble is, I got it back with a full chain oil tank, puty it in the shed and didn't use it at all, went to move it aside the other day and it's ****** most of it onto the shed floor! Having taken the side cover off I can see the end of the feed hose from the lubricator trhough a hole in the chain bar and I can remember tehre being something in the bar on teh last one blocking my view. Looking on the 'net it seems the petrol ones have a felt washer or some sort of seal to stop the oil pi55ing out, can anyone confirm this please?
