As another Lame Cherry exclusive in matter anti matter.
A few years ago in the coof, I started acquiring some back up chainsaws, namely the Poulan 2000, which are now 25 years old. The mother had one, I used it, it was a good saw, and I was getting familiar with in how to fix it, in watching others and my own experience.
I like the saw as there is no primer bulb. You take two screws out and the inner workings of the carb are all there. So I can dump gas into the carb, pull it over and see if it starts. This time I needed Jimmy who is Rick's friend, a savant on electronics and carbs, to get the one going I had been dinking around on, and he did that.
This though is the story of a replacement from Ebay which I thought was all there, but when I put in a new fuel line and filter the front cover for the carb was gone. In most of these saws that are junked or not running, they just need the tank flushed, a new fuel line and filter installed, primed a bit and they will run. It is stupid what people throw away
I do not monkey with springs, needles or fuel screw adjustments.
In this case, I put in the fuel line and wondered why this carb was leaking. No front, so the gas was coming out. When I picked up my saw from Jimmy's, I asked if he had a front cover. He happened to have one and gave it to me. See they do not make carbs of this Walbro style anymore. You can get them, but they have the double fuel line in the fuel and the primer, so you have to plug the primer as there are none on these older 2000's.
So I came home and started the adventure the next day. I knew the cover was not quite right, but went ahead as I had a carb tune up kit with the diaphragms and got things installed right as you have to watch to make sure they are in right. (Jimmy said I messed up on the one I had installed and apparently the little nipple on the main diaphragm needs another gasket to keep it off the needle so gas will flow. Something else I learned for 40 bucks as I ask allot of questions and most mechanics are good teachers in telling you things.) If you are not a complete asshole.
So I have below what the front cover should look like. The one Jimmy gave me did not have that screw on it, but I installed it anyway as it fit.
Put in gas, and it fired right up in a few pulls. This saw though the throttle switch will get stuck up in the handle. I will have to remedy that with a screw or trim with a utility knife, but I was pleased it ran like a top.
I noticed though that it would not idle down as it would quit. The Holy Ghost explained to me then the mystery of what I was puzzled over in that screw, circled above rests on a cam eccentric which is attached to the throttle rod. That screw is the idle speed screw. Has nothing to do with gas metering, but handles the engine RPM at idle. That is why when I kept my finger on the throttle it idled and when off it quit.
There are different holes in this cam. The #2 is the one Poulan sets in, but I wonder if I put it in the #1 if it will idle on it's own without that screw as a free cover is better than costing me money as I can work around this.
Other than that, I need a bar and chain 16 inche, 52 link, and I should be good to go. The engine is really good on this saw. I will find a filter for it which I will make as not spending 15 bucks for one, and then we should be good to go.
The air chamber though was packed solid and I mean PACKED with fine saw dust. How someone would run a saw and not at least look at it, is one of those things outside the Brier. Getting that dug out was the longest part of this adventure.
This stuff is not for everyone. I'm kind of self educated and have watched JYG, Tractor Whisperer and Jimmy fix things and I pay attention as I pay for the lesson. It is sometimes over my head as I do not have a shop, from non donors so I do have to turn to oldsters who are dying out as the kids all want 150 an hour to give you a saw which will not run.
Jimmy had a Walbro W gauge to measure the height of the needle flipper which he showed me. He is one of the nicest and quietest people there is. I would that I knew what he knew, as he said to me, "Those chainsaws and weed trimmers are a pain in the ass. Most of them come in here and they do not run. This one at least started running". I'm the person if I show up for something to fix, all the easy stuff has been worked through and there is something really wrong.
These guys though mostly never throw anything away. Have parts up the ass and things you would never dream of, but you ask, and from pile or a corner, appears what you are talking about, in their one of a kind filing system.
If you treat these saws with some care, and that is mostly ALWAYS clean fuel, and for me, not recommending this for all saws, but for me, I put in a Pennzoil two cycle. I never mix up a batch. What I do for this Poulan is a cap full of the blue oil into the tank, fill it up with gasoline (non ethanol as the alcohol makes the diaphragm parts stiffer) and it is quick and easy out of the little plastic gas gallon jug I got........covered over on the spout with a latex glove (nitril works better as gas degrades latex).
I like these saws. See them appearing on Ebay yet, sometimes way too much, and other times are a good deal. They get old and quirky but that is part of this in I know what the nuances are in the saws so they run. If I had the cash I would probably buy a couple more as when I have success like in this saw, it makes me feel confidant in I can get anything running again. Just be careful ALWAYS in never getting dirt or sawdust into your gasoline tank. That is where most problems come from.
I just have to start collecting junk chainsaws more so I can get a pile of spare parts as someday I might have time and a shed to play with this stuff like the guys on the tube do.
