Looked like an 18....mebbe a 20. I was more interested in the other details and sizing up the seller than the b/c specs, though there was clearly some life left in the chain. And isn't it an oddball pitch/gauge combo of some kind?

No way could that runt pull a 1/2" chain. It would mostly be 3/8 pitch but could have also been .404
From your description, that $40 seems in the range. That was a farmer saw. Ask him to offer it to his appraiser for $300 and see if he buys it.

I love mine to. Cuts great, I just have to work out the kinks. I think it lacks in the air filter department though.The saw is suppose to run out of fuel before bar oil is empty. I think that is standard procedure on all saws. I use 4000's quite a bit. I have used this series of saws for 20+ years. Over the years you just get into a habit of pumping the manual oiler every so often while cutting without thinking about it.First thing I would ck is the black rubber pick-up tube with the spring & weight on it. They have been known to break over time, usually right where that spring is. Other than that, the diaphragm might be week. Some of the real smart fellas on here have made new ones.
I never have.
As far as the air filter goes. I carry a soft bristled brush in with my other gear while out cutting. When I refill the saw, I just take the filter off and brush it clean. Don't take but a minute. I do the same with the flocked filters of the 3400/3700 style also. I have never had a problem with them, they seem to do the job! The 4000 is probably my favorite all around saw. Can ya tell? LOL
Gregg,
I do not have any Poulan 4000's but I do have a couple of Poulan 395's and they use the same air filter. I really do not have a problem with them. Actually I prefer the screen type filters over the flocked ones. Heck I even took the flocked filter off one of my 3700's, and removed the flocking and glued in a screen that I had bought.

I dont have any problems with large chips getting through. Its the fine particulate I am having trouble with. The throat of the carb gets a even light film of dust throughout it.
Well the screen filters probably do not remove the very tiny particles as well as the flocked filters but they do flow air better so what you have is a trade off. I myself prefer the air flow.
I also find with a good sharp chain I do not get that fine saw dust so much.
Aggree with 3000 FPS.I've figured that a not sharp chain produce a lot of dust which blocking the air filter but it also make the chain dry.The large chips cannot imbibe to much oil but dust can.I was cutting the other day with my 4200 with a allmost dull chain.I was sure that the oil pump was able to oil the chain with only 1/4 of a turn in the screw.Well,i had the screw all the way out and for a moment i saw the chain was smoking.I stopped,back home,new chain and everything was as they should.not to mention that after 2 tanks the air filter has so much dust on it and the saw was barely able to rev.
I wouldn't worry to much over that, the fine dust that might accumulate at the throat of the carb. The fine spray back from the carb I think keeps it moist is why it accumulates there, just wipe it off when ya service the saw. This series of saws have been out there and running since approx, 1980. Thats over 30 years. And I have seen very few that were damaged internally. And I have had my hands on a lot of them..
Here is a picture I posted once before, of some of the horrendous condition of air filters I have come across on these. And the saws continue to perform. Its amazing really. So I wouldn't loose much sleep over the slight dust accumulation on the outside of the carb. Obviously it would be nice not to see it. But, I don't let it bother me.
Gregg,
it is sad that folks do not take care of their small engine equipment and wonder why they break down. Folks think they can buy equipment and it will run forever with zero maintenance. If it was not for those folks though we would not have half the saws we have.
Like most others here I have never seen much problem with the filter setup on a 4000 period and back in the day they were built it was as good as any made then.
It sure is as good today as what you would find on a farm boss.
The 4000 is a very tough saw, you should see what some h have gone through and are still out cutting wood.
If you think you really have a problem why not cut a piece from a Briggs pre filter and lay up under the stock filter.
At least they had filters, albeit useless! About half the 3400/4000s ive had have had no filter and one had a sponge jammed in there.I wouldn't worry to much over that, the fine dust that might accumulate at the throat of the carb.

Gregg,
it is amazing how much saw dust can get into the fuel tank when the vent line is missing, clogging the carb screen and or filling up the diaphram area. I cleaned a Tillitson and walbro today that had me amazed at how dirty they were.
Gregg, at least some of them filters kept rocks out. I've had stihl filters come in the same way, just bare wire left.

Made a cool banner today using one of my fav 85cc saws to run stock for stock. 
Now to find one with poulan bars used or other good looking bars.

I think I just might let it be. I will go through the oiler system and report back. As for the chain being dull, I always keep my chains sharp and the drags set at .030. It seems to like the stihl full chisel I put on it.
