Ms290 oiling but it never reaches chain

[jakethesnake]

Found this odd.

longer story this saw was scored. New meteor piston caber ring.

all well but never did oil. Just oiled the side of the case.

Found something interesting.

Guys ever seen anything like this?

Fuggin stihl

I’m just going to spot over this with jb weld. Good enough for who it’s for
(It’s mine)
Not gonna sell it ever.
Not a huge stihl fan but for what this thing is the few test cuts I’ve made with it it’s a pretty good saw for firewood. Fairly close to a 455 husky is my opinion.

If you still have oiler out and a dremel you can port that thang.

I was never happy with the way my 290 oiled.

I didn’t bother modding the pump. I did test briefly. Noodled up some bone dry mulberry from firewood pile. I’m pretty satisfied as is. No oil leaks Runs great. One of those unfinished projects complete

I ran into an MS290 this past fall that would oil neither the chain nor the bar. I replaced the pump, the oil line, and the filter, and it still would oil neither the bar nor the chain. The oil slot/port on the housing lined up with the bar OK, but no oil would make it to the port. I gave up, charged the owner nothing, and he saved the saw for parts.

First time that ever happened to me with any saw, but it did happen. If anyone has any suggestions, feel free to offer them. The saw's engine runs fine and is still intact in the boneyard. Rather sad.

Will it oil without a bar on it?

Nope. No bar oil comes out the case port. This saw rests in the owner's bone yard.

Mine was oiling everything but not making it to the port either. Ouled my leg and such. I missed the problem multiple times.

Ever check the tank vent?

 

[Wood Doctor]

Ever check the tank vent?

The IPL doesn't show any "tank vent" except for fuel. What part is that? The valve (1128 640 9199)? Can that get clogged up somehow and stymie the pump? Seems precarious. TIA.

I partially plugged an oil tank vent on a Husky 257 and it pumped even more oil afterwards. It seems a wide open vent was slowing down the pump, just the opposite of what I expected.

Yeah that thing by the studs.


And that's a head scratcher for sure on the 257.

As shown in the diagram, you have to knock that "thing" (valve) out and replace it. I suppose it's worth a try. That part is the same on several Stihl models. I tried to simply open the small opening in the valve with a needle and that failed to do anything.

I also agree that the 257 replacement I made should have slowed down the oil flow rather than speed it up. I'll keep watching it and report back, but it already kicked out a full tank to the bar and the saw ran fine while doing so.

Maybe just hit the valve with some air.

Make sure the tank is empty first, don't be like me lol.

Thanks, Dub, I will do that. I have a tire inflater that might do the trick. I'll try that first. If it fails, I will replace the valve. If that fails, I'll drop the saw back in the bone yard. I've never seen anything quite like this with any Stihl that I have ever worked on. Thanks again.
