Re: Bar chain oil, not flowing?

Hi Guys,
Partial success:
Emptied both oil tanks and flushed them out with diesel,  half filled them with diesel and then ran the engines up and saw fluid coming out of both oil holes.
The 271 seems fine now, I am using the last 3 litres of 'Best green oil' with a 10% addition of diesel to thin it down a bit; I will dump the rest get some fresh.
The old oil is indeed vegetable, so I guess that it had gone off due to its age.

The 390, I flushed it out too, got diesel coming through, but seem to get quite a lot of air bubbles as well!!!, it pumps oil out when running (without chain) i.e. the reservoir fills up where the bar would sit against,  but I am not sure that enough oil is coming through and a bit worried about the air bubbles which I didnt see on the 271.
The oil only comes out of both when the chain guard is released !! this seems quite logical but is it right ?
The chain does not seem to get that oily - brand new bar and chain on, so no chance that the oil hole is blocked.

I will have a look at the filter on the end of the little pipe in the tank next, I guess this will mean I will have to strip it down a little.

I was thinking of blowing air through the outlet hole, but not sure that it is a good idea to put pressure through valves and worm drive etc.

Thanks for the replies so far, much appreciated
