Perhaps oil thickened inside feed tube or dust
got in with the oil....or sawdust got up the tube from
outside.....tip the oil out and fill with a thinner material
like petrol or paraffin..slosh around...try to get it to
feed out....obviously not with it running especially if
you are using petrol...or perhaps then tip contents out
and see if a lighter oil, like paraffin will feed through....
....how about sucking on the feed tube from the outside or trying to poke out an obstruction with a fine
wire or a pipe cleaner....I would try sucking it out first
with a straw to avoid forcing it further in....perhaps get a little syringe from the chemist, fill with petrol or
thinners and shoot that up the feed tube exit point....
it could soften the thickened oil and let the obstruction
out...maybe with the empty syringe if it has a small
enough tip, you could use it to suck the bit out...
maybe try the crevice tool on the vacuum to suck it out or gaffer tape on a tiny tube temporarily to increase the suction and get it further up the tube...I suppose the last bit would be to take it apart and perhaps replace the oil pump...not expensive...sometimes the diaphraghms dissolve with age and the bits clog the line...there is a place which I found near Worcester which deals in McCulloch bits.
Let me know if you need it...I could look it up

Good luck.
