Thank you for taking the time to reply, yes I agree and will definitely give it a rinse, is diesel or petrol best?

Hi, many thanks for replying, to be honest I am not sure what it is... best guess was a sump plug. I have attached a photo of it from the underside and the filter to see if this helps to identify what it is.... Just can’t understand why it didn’t drain out the full tank of oil when removed, so assume it must be a separate tank, but unsure of its purpose if that’s the case.... Thanks for the tip on cleaning the oil pump feed line out, I will try that next and tank flush.

Does anyone know why this would be the case? Saw has recently had a new bar, chain and an oil pump, as I thought that it was the pump that was at fault. With the oil tank is full and after 20 mins use the chain was dry, tight, hot and no sign of oil level dropping in the tank. With the bar removed, I can see only a small amount of oil / bubbles coming out of the outlet when running. I’ve also set the pump adjustment screw to the maximum, but this makes no difference. I’ve also noticed something strange when I removed the oil tank sump plug/filter (not the oil filler cap) from underneath and no oil drained out what so ever, even though the oil tank was full!? should it have drained any oil out, unexpected, or could it be blocked somewhere? Next steps would be to flush the tank with fuel and hopefully this removes any debris/blockages, but failing that, I am out of ideas. If anyone could help diagnose this I would be most appreciative. Otherwise the saw runs well and it is a shame to mothball it for the sake of this issue! Thanks in advance.
