Well as it says, this is going to seem a daft question.
Having, at long last, bought myself an oil can (reservoir, spout and pump lever type - is that really the correct description?), I can't seem to get any oil out. The 'bottle' is more than half full, I've tried priming it with oil down the outlet (the flexible spout unscrews) all to no avail. What am I missing, it can't be that hard can it.
