191t not oiling.

I blew throught it and felt air out the other side. So it's not clogged. Do oilers have some kind of pump? What else could it be? Thanks

Yeah, they have an oil pump. I don't know about the 191's though...how they work. Some work differently than others.

Unless they changed things from the 019T there is an oil tank vent under the case near the fill spout. It is a little rubber grommet with a tiny hole in it. My O19T quit oiling-cleaned the pump. Oiledfor one tank-then quit again. It oiled off and on -just barely- until I reamed out the vent with a bit of wire. Now it oils fine.

I will look for a vent. But to clear something up, it's a Stihl 191t. Is that a type o
stumper of are you talking about a different saw. Thanks guys.

Any resolution on this topic? My MS191t isn't oiling either. I don't see any vent. I guess I will try to do a partial disassembly to see what I can see.

Yes, I got it working good. It took much more than I thought. I used my compressor and the blower and an ice pic. The final push was with kerosene. I cleaned out, blew out, poked around ran it with kerosene as oil. (severel times) And now it works well. Don't take that saw apart if you haven't already. It is really hard to work on. I couldn't get my throttle back together for the life of me. I used the ice pic to get the filter out though it was clean by looking at it but then I cleaned it up with kerosene. Never did find out what was clogging it though.

Hey, by the way, welcome to the Arborsite!

Whoa, I was just about to go down to the basement and disassemble it. So there is an oil pickup similar to the fuel pickup? This gets clogged somehow? Kerosene sounds like a good idea. Thanks!

There's a thread on here I was reading the other day I look for it about how hard that saw is to work on. So try all else before taking that handle apart. I never got to the oil tank anyway. And if there's something I know how to do is take stuff apart. Keep working it like I said you'll get it to work.

Here you go, read this thread.

It's really juicy if you have one of these saws.

Well, I finally buy a Stihl and of course it's going to be the worst one ever made.

Tried a dose of kerosene and some poking with a wire but no instant success. I'll try running it more tomorrow (w/o bar). Thanks.

Actually, when I bought my saw, I was buying a cheap saw. But after reading that I was impressed. Didn't realize the thing had such good power. I'ts just hard to work on. Luckily mine hasn't been any problem execpt for the oiler. And that was just a cleaning.

I bought mine to replace an old Mini-Mac 6, which is a very similar but ancient saw. This Stihl has always had a tendency to die just as I have reached the top of the ladder.

Update: I now have a small amount of kerosene flow, but how fast does it need to drip before I can deem it cured? Thanks.

Another question occurs to me: Is there a thinner bar oil for Winter use?
