Chainsaw Repair

well one thing I've learned over the years is sometimes things just don't make sense. the laws of physics can be thrown out the window more times than can be explained.
I've worked with many fluids/liquids that will (given the opportunity), will flow up hill to empty a pail, bowl or bottle due to their 'ropey' bond structure. you get the stuff flowing and it will pull itself up and over (sometimes at great distances), and thick chain oil is no different.
one liquid that comes to mind is any 'flocking' agent. you can have a 5gal pail full of it, start pouring it at a sharp angle, then set the pail back down on it's bottom and it will empty itself out. you need to tip that bucket back and stop the flow. egg white will do the same thing.

at any rate, changed the line and grommet and it still wanted to come out of the port. also changed out the vent with a new one. ended up switching the oil pump out with a good used one and the problem went away. threw the suspected pump on the parts saw and can't get it to show the same issue. so I guess when I get around to fixing that saw up, I don't have to worry about the oiler dumping oil all over the shelf. maybe. we'll see after it runs for a while.
