![]() ![]() ![]() I can't see any visible damage, but that may have contributed to the poor cutting. I got the bar pinched in a tree a couple weeks ago. I've sharpened it repeatedly, but it doesn't seem to cut well anymore. That could be partly due to the dull chain I suppose. A carb responds primarily to the velocity of the air moving through it, which is volume per second, rather than density. The Stihl 021 has served me well, though it has been bogging down on me a lot lately. Chris-PA said: Pretty straightforward: Air expands as it gets hotter, which means more distance between molecules, so a given volume of air holds fewer molecules. If not, I can't really justify the added expense. Primarily is the new saw going to start any better than my current one. So I don't want to fork over the cash unless there are real advantages to upgrading. $65 in parts to fix the old one is still better than $400 for a new saw. So that's one of the main reasons I was looking at a bigger saw like the 271. The 16" bar and low power of the 021 aren't exactly ideal for that. I've been experimenting with cutting lumber from trees I've cut down. ![]() The 021 has served me well, though it has been bogging down on me a lot lately. Cost me about half of what I paid for the saw in the first place, but in the end it didn't start or run any better than before. So I took it to the local Stihl shop and they rebuilt everything. I normally do all the work on my own tools, but since it was always hard to start I figured I must not know what I'm doing. What would you do? Fix up the 021 again, or replace it the MS271? But, I still think some of my projects are larger than I could handle with a battery saw. Grab and go, no fuel mixing, or cords to drag around. The longer 18" bar and a bit more power would be nice, but if I'm going to have the same starting issues there's not much point in upgrading.Ĭonsidering how infrequently I use the saw, I've been tempted to switch to a battery powered saw. I've already dumped over $200 in repair and maintenance costs over the years.īefore I spend more money on this saw, I thought I would look at newer saws, specifically the MS271 Farm Boss. I'm getting too old to fight with my saw when I need it.Īnyway, I was going to replace the bar and chain, to the tune of $65 or so. I always use fresh fuel that I have added fuel stabilizer to. I don't use the saw that often, but when I need it I hate fighting with it just to cut up a tree that fell over. There doesn't seem to be any pattern to it, sometimes it will start, other times I can pull the cord for 30 minutes with no luck. I've tried with choke, without choke, every conceivable throttle setting, and pulling the spark plug to clear fuel from the cylinder. Once it is warm, it is nearly impossible to start again. When it's cold it will usually start with a few pulls. I had the local Stihl shop overhaul it a few years ago, but it is still difficult to start. Overall I have been happy with it, but I have had problems starting it since the day I bought it. I have a Stihl 021 with a 16" bar I bought about 15 years ago. ![]()
