A little known fact from our country's history, is that Indiana
was actually a penal colony, where all of the riff-raff from europe
was sent. Kind of like Australia, but with bigger mosquitoes.
So the lowlifes that post here from Indiana, need to be ignored!
Michigan was North America's version of Devil's Island for
France, so giving them chainsaws was a bad idea.
As far as the oiler goes, dump out the oil, then rinse the tank
a few times with gas or mineral spirits, then run the saw a
few minutes with the bar off, and check for flow.
If it improves, dump it out and add oil, then check for flow
again. It may have one of those cheap Poulan oilers, which
replacing them is not too costly, like $9.
