Hi all,
Working on a homelite 240 chainsaw that runs like a top,but the auto oiler isn't working.
I have checked the oil pump and it seems ok, all hoses check out also.
Nothing is cloged at the bar all blow clear.
I did not pull it all the way down to check the pump vacum end,but that
blows clear also.
How can I tell if the pump is good? The diafram is intact.
Problem seems to be pointing to the pump.
Thanks for your thoughts...........

That's just what I did do.
I even dropped some thiner oil in there and worked it around.
Do I have to put the bar on to test it? :confused:
I just tried running it with the bar off and didn't have oil comming out the hole.
I checked around for a new pump,few to be had the one I did see was $37
Might be better off putting that toward a new saw.
Bill or 30 year? are these homelites known for bad oil pumps?
