I have a Stihl MS 290 which has a 20 inch bar / chain. It's the one I use for "bigger" work. Any bigger than that I hire it done. But I've had this machine for 20 years, at least. It's been a pretty good saw. A few years ago, it wouldn't fire, so I sent away for a coil kit. Which I changed and it fired right up. I may have replaced the carb. somewhere along the line, too. But lately it's been sitting for at least a year. About a week ago, we had a blow that toppled a big upper branch off of an old maple tree. I have a Stihl chain saw with a 16 inch bar / chain, and I use that to clean off all the little stuff before I get to the major branches. For those I change over to the 20 inch saw. When I did that last week, I couldn't get the 20 inch to fire. I tried all the little tricks to nurse it back, nothing doing.
Mind you, I try to use non-ethanol gasoline for my small engine equipment. Been doing it for years. But a few years ago, the place I used to buy it changed ownership and no longer sells it. So sometime since then, I ran out, got lazy, and started using gas station fuel mixed with oil. And this may be part of the problem. Friday, I got two gallons of non-ethanol gasoline at a special place. 92 octane, $6 a gallon, they sell it to people with older performance cars too. I think in some places, it's sold as Rec-90 fuel. You can get it at some boat docks too.
First idea, to look into getting a brand new Stihl 290 replacement. After all, my present one is at least 20 years old. And, one thing I will never do is buy a used chain saw. Enough said about that. Thinking new is because I know how much the boys at the Stihl store charge and my 290 needs a bit of work. And, I need it right now. Knowing that replacing the MS 290 would be an approximately $500 to $600 proposition at the Stihl store, I decided to look online to see if Amazon sells the Stihl brand. If they sell something branded Stihl that is comparable to my MS 290, I didn't see it. What caught my attention was the cheap Chinese-made 20 inch chain saw for $113. I'm thinking, "How bad can it be?" I decided to gamble that amount and find out. At the same time, I also ordered a rebuild kit for my MS 290, which includes a new coil, new carb, air filter, blah blah blah, probably also made in China.
The Amazon seller of these saws sells them under the Pinc and Wemars brands. They seem interchangeable in order fulfilment. What I got was a Wemars. Petrol chain saw. The instructions, allegedly in English, are typical of those furnished with lots of Chinese stuff with more that two moving parts. In other words, almost unintelligible. I don't get it. The Chinese have been selling junk to Americans for a few decades, haven't they found someone yet who translates English so we can understand it?? If they can't find such a person in China, would it cost all that much to have an American do the translation here, then send it back to them for printing???
Anyway, the new Wemars instructions do not match the machine I got. The controls are a bit different. There is a supplementary sheet that shows a different design saw with different controls, and this one doesn't match the machine I got either. I'm used to the Stihl throttle lockout lever on top of the handle. So you can set the throttle at about half for start-up. Which is tied in with the choke. The Wemars has this lockout lever, but it doesn't do anything. There is no provision to fix the lockout lever in position to hold the throttle partially open. The instructions (that don't match my saw) show a button to set the lever, but it's not present on my machine. What my Wemars has is a manual choke. Maybe it doesn't need the throttle locked half in to start. Because it seems to start fine leaving the throttle closed and using the choke. Maybe the lockout lever is just there, doing nothing, because they had X number of such handles left over when they changed design. Waste not, want not. But please give me something in the instructions about my specific saw.
The saw ran like a scalded dog yesterday and today. It started cold and hot flawlessly on both days. So I have no complaints about my $113 saw. Which it occurred to me that I'd better buy before the Chinese ships quit coming to our shores.
Now that I've got the repair kit for the MS 290, I'll work on that in my spare time.
