Chainsaws....

I have used a lot of different saws, and I'll tell ya what about the oil leaks.
Most saw companies went to a gravity feed chain oil system that literally just seeps oil through an orifice that just keeps running even though the saw isn't.

I store mine with the starter side up so the bar oiling orifice is above the oil level.
Try it, and you will probably find out that this is what is causing it.

I have Poulan Pro 20 now, but I used to run a 40 inch 14 hp monster Homelite every summer getting wood and it had a manual thumb pump oiler.
My Dad bought me my first chainsaw for my 12th birthday and up till then I used a double headed axe to clear the limbs off so my Dad could cut the rounds.

Of course this was a lifetime ago in the Sierra's and I just cut stuff around the house now thank God.
