Ok men, this ones open to both constructive comments as well as wisecracks.

A customer of mine, and he's a "Prooooo", brings me a 335T that he says isn't oiling right. So I take off the bar, blow it out and fire it up. Saw pumps plenty of oil. Call the customer and tell him that it's fine. He tells me it isn't. Says that he can't get through more than half a tank of fuel, without having to stop because the saw isn't oiling. "So what happens then"?, I ask. He says he has to clean it out and then it's OK for another half tank. Ok, I tell him, if the problem is solved by cleaning it out, then that's the problem. If the saw is pumping oil, then the saw is OK.

Now this customer is OK, but he's kind of one of those passive/aggressive types, and he strikes you as someone who smoked a little too much weed when he was younger. He goes on to insist that there is still something wrong with the saw, because it shouldn't get that dirty that fast. None of his other saws get clogged up that quick.

Variables and stuff I checked: The saw is loaded with pine pitch, so I think that might have been a contributing factor. I checked to see if his chain was sharp, in case he was throwing more dust than chips. It does have one of those stupid "intenz" bars, but I never saw one cause an oiling problem. The final thing, which may be the culprit, is that this guy uses some kind of vegatable oil for bar oil. (remember, we are near Woodstock!!) I don't know if it's something that's made for saws, or if he got it from the health food store.

I've got some pole wood to cut up here at the house, so I'll take it home and put some regular oil in it and try it myself. If it passes that test, I'll hand it back to him and get one of those blank stares in return.

So, what do you think?
 
How long does it sit between runnings?
The only real problem I have heard of using Canola oil, not sure about the others yet, is it will gum up if it sits to long. Maybe it sat enough to get a ball of crap that will plug up the line after running a bit?
I dunno?
 
intenz bars

Another thing to check is the oil delivery holes in the bar, some of them got over painted an closed up the holes. A small drill can open them up. Second thing to check is with the intenz bar is how tight he keeps the chain, if he keeps it loose on the bar the end of the bar clogs, the rail fills with sawdust and covers the oil hole. Doesn't sound like he clears the rails of sawdust. I have a couple intenz bars I use on the smaller saws and these were the problems I found.
 
It's the oil tank vent. If it's the old style they're a pita to clean or change. Easiest route is to put a oil cap from a 2100 on it. These caps are vented and fit like a glove.

Thanks Gregg; I'll take a look at that. The other thing that I want to check is if at the half tank point, the pump is still pushing oil.

And you're right, these things aren't the most fun model to work on!
 
What clued me in is when you said it pumped a half tank then stopped. Then after he removed the cap and checked the oil it started pumping again because he relieved the vacuum. When it's only half full of oil there is much more air in the tank, and it can't build enough vacuum again to make it quit oiling before it's out of oil.
 
Any update here? Grande Dog's guess makes sense.

WHen my 371 was pretty new the oiler would work and then not work, eventually not working at all. TUrns out the tangs on the end of the plastic propeller that drove the oil pump had worn down to where first they didn't catch all the time and eventually didn't catch at all.

Turns out it was enough of a problem Husky changed that part. WHen I replaced mine I bought an extra and have never needed it.

A friend once had a flat shaving that was sitting at the bottom of the bar groove right near the bar oil hole which acted like a flapper valve. Would sometimes block the oil. It was really thin and somehow it had managed to elude being removed when he cleaned his bar for a short time. I found it and once gone problem solved.
