Chainsaw Repair

So....
I finally got to cleaning this saw up.
Every part cleaned, no damage, all is working fine.....except the oiler. The first test was with 10w30. It barely pumps at all. with the chain off it blows bubbles, and doesnt do much but drool oil....slowly.
Running it bar and chain on, its almost flinging a tiny bit of oil.

Maybe the oil is too thin and isnt making a good seal in the pump shaft. Lets try heavy bar oil.

Same. 

The little brass screened vent seems to me to not let much air flow, I put a small hose on it tight and blew through it, it barely lets air in, suck on it and no air at all goes in. So with the bubbles I figure its must just not be breathing.

This little screen is impossible to remove unless you destroy it and I didnt have a new one. So I drilled a very small hole in the oil cap.
Yes, it leaks oil out this hole. But, when you rev it up it sucks the oil back in. It gets on the bar, flings a little oil, and seems to leak more oil where the bar is bolted to the saw, actually. The bar gets oiled, more or less. it doesnt get hot so I assume it is getting enough. It sure doesnt fling oil like it did the first week but whatever, it might as time goes on.

To cure the hole in the cap drooling problem, I made the hole slightly larger and forced a red spray can stem (the ones you lose off the can the first day anyhow) into the hole, its a tight fit. I bent it in an L shape carefully so not to kink it, and pointed the end UP in the air so its higher than the tank. Its too short but I have a roll of that stuff here somewhere I will male a longer vent hose and tuck it up higher out of the way... and it no longer drools oil and can still breathe.

I was going to just let husky fix it but after talking to the service dude, he said its $60 an hour, Husky has never paid for a new oiler or vent valve/screen for his work as they call it a wear part, if it plugs up or stops pumping, its somehow a user error that caused it after a few weeks of ownership.

True? I dunno. I dont have time to screw with them nor do I care to pay this guy $60 an hour to fiddle with it till it works.

Later on I will pit a new $12 oil pump assembly on it, Ebay parts are cheap and new.  That may work but I cant see why, the pump fits snug and spins easy, the flat tip of the shaft seems to me to be a little small for the job but it did fling well to begin with.

I see replacement shafts on Ebay that are identical, but the half flat end on the shaft is much longer. If they fit this might be a real easy fix for a few bucks.

For now, it drips oil on my boots, flings just enough to keep a film of oil on the bar groove and its getting more than enough oil under the clutch cover to make it drip on my boots so... more oil isnt a bad thing I guess.

If it didnt run so nice and start so easy, I would take it back to Lowes and demand a new saw but its way past its store warranty time so that would probably be a lost cause.

There has to be a proper fix, I just havent found it yet.

I was so irritated I forgot to take pics. Sorry. 

I wonder if the intake stem in the tank is not letting it suck oil hard enough, it seems clear when you blow air into it...

Meanwhile, the $99 poulan I used to cut up pallets is still after 10 years flinging oil, starting easy and running all day with no problem.
Lesson? Never pay more than $99 for a chainsaw.
 

The oil pickup tube/screen is not very expensive

You can try some kerosene in it?

It most likely comes out from the pump side?

To deal with the pump you will have to remove all the clutch assembly. It is threaded on with left hand threads

I've had it apart several times....

You'd think taking the pump off would give you access.   
Not so, in this new saw you see a molded square depression with a hole in the side. No access to the pickup tube nor can you even see it.  You can see it through the oil fill cap, and it is grey plastic clearly mounted.....somehow in the orange plastic body.

I grabbed it with long forcepts, its in thee tight. I thought it might just snuggly fit into a hole but no its in there solid.

There must be a trick to getting it out.

I thought the part that the pumps sits on pulled out and the pickup tube with it.   It does not come out from the tank filler hole.
