Four stroke chainsaw at Lowes

[cookies]

i'd be interested in seeing the rpm it turns using a tach, bet its low for a saw. I'm guessing something like 5800 max rpm...a big sprocket and short bar might make it more useable or a bigger carb, alcohol fuel, deck the head and bit of timing advance

Got a real spark plug in it, got the special screwdrivers in, and got it tuned better. Out of the box, it wouldn't even stay running, but it's a legit saw now. You can lean on it far more than a 46cc saw has any right to pull and it just keeps chugging. I'm pretty impressed. Wish I had more wood to try it on.

This is a viable choice for the homeowner who can do a couple minor things to the saw and doesn't want to keep mixed fuel around.

If development had been put into 2 strokes along with 4 strokes(and the rules didn't unfairly favour 4 strokes), things would be different in motocross. The superiority of the two stroke dirt bike is evident by the fact that they still even exist.

As with most things 2 different engine designs there are pros and cons to both. Sometimes I prefer the high rev 2 smokers and other times I like the low end torque of a 4 stroke. 2 smokers are light and easy and cheaper to fix not so much for the 4's The same argument could be had between water cooled vs air cooled. As for what came first the 2 or 4 stroke but both have been around about the same time. 4 strokes do preform as well or better then 2 strokes do. The main difference is in weight vs burning oil with the fuel. They don't call them 2 smokers for nothing. The advantage of a 2 stroke is they will run in any angle, right side up or up side down it doesn't mater. 4 strokes don't do well running upside down.

I put an NGK plug in it yesterday. Definitely better, but still issues. Waiting on carb screwdrivers to arrive, any time now.

It's like an 80% lower chainsaw kit. A lot of the important bits are there, but it's definitely not a functional chainsaw as received.

@Franny K Confirmed, no air pollution clean air whatever anywhere on the packaging.

I had to put the chain oiler together properly on mine too. It's like a reed valve in a housing behind the clutch. The reed valve was not in the locating grooves so it only half covered the hole in the crankcase. It must work on crankcase pressure as the piston goes up and down

Seems like a catch to me...
Average homeowner that doesn't want to keep two cycle fuel around isn't likely able to tweak cheap 4cycle chainsaw to get it to operate to the point it isn't a hazard to one self.

Homeowner level gas saws are a catch. Two stroke or four stroke, that niche is essentially dead.

If you're a homeowner with the occasional downed limb to take care of, go get an electric saw and avoid all the hassle.

If you're a firewood guy who has a decent amount of cutting to do, spend a little more and get a real saw. This saw was $179, there are two NIB CS590s on Offerup right now for $200 each. Even from Home Depot, they're only a couple hundred bucks more. It doesn't take much more money to get into a lot more saw.

I prefer the double d myself lol but that’s because I’m really only 12 on the inside

None of those. Open circle with a little dot closer to one edge. I type "dot in the corner" at first, but there's no corner on a circle.

This kit, the larger "acircle" driver:

I got like 3 sets now. Think I have the dot one. But never needed to date.

This is the same one as sold at Aldi here in Australia. I bought one for my parents - Dad is getting on and the 1967 model Stihl is a handful at the best of times. They live off grid out in the bush so an electric saw was not practical so I got this. I have the earlier model, and while i didnt get a chance to use this one myself, it looks to be a much better designed and made than mine - and I quite like mine

I havent had a go with it, but Dad reports back that its a good saw. It gets used on greybox and ironbark timber (species of Eucaltyps) which is pretty bloody hard wood (burns really hot though ). Dad said the first start out of the box took quite a while to get it going, but since its been perfect starting straight every time.

It gets properly used (firewood being their only heating), so will be interesting to see how long it lasts. Not as long as the 50 year old Stihl that still going strong is my guess!!

There is one labeled 49cc for$169.99 at Tractor Supply, well two as of yesterday on the shelf.

 

[OM617YOTA]

Looks like exactly the same thing.

Still need to put some serious trigger time on mine, don't even have a tank of fuel through it yet.

Wonder how they would respond to a muffler mod, or any other mod for that matter.

 

[67L36Driver]

Would there be a downside to feeding it two stroke mix fuel?

I don’t keep any straight gas on hand because of the danger of messing up a real saw.

My little Briggs mower has run mostly saw mix with no ill affects. Well, not yet. [emoji848]

You will lose power because your gas is cut with oil and that means a small reduction in BTUs to provide power. And eventually, even at 50:1 I’m sure your plug will get darkened up a bit. Never heard of using premix in a four stroke, on purpose, but if it works for you.....go for it

I would think that the effects on a small engine would be greater than on a larger one.
I was always told to dump my older mixed gas into my car's tank to keep from wasting it.

 

[OM617YOTA]

I'd be willing to try a muffler mod, after I get some timed cuts while stock for comparison.

I plan to try a more aggressive chain before the muffler mod. It's got round corner skip safety chain on it right now, need to get a loop of full comp chisel. I was poking fun at the size of the dogs in the video, but this thing is a torque monster. Dog in hard and let it eat.

I expect two stroke fuel would run just fine.

I don't buy the more oil = less fuel argument anymore. Back in the days of castor oils, where you'd have schmoo running out the muffler, no the oil isn't burning, just making a mess. Modern oils, the oil burns and contributes to the BTU content of the mix, and doesn't fill your muffler with schmoo. Like any saw, tune for what you're running.

I had to richen up the carb mix quite a bit to get it to run right. Adding two stroke oil might be a good way to do that without messing with the carb.

 

[GeorgiaVol]

So if you increased the compression, you would need more octane right?
Lol

I think that isn’t a bad idea on a news engine. But it wouldn’t be the best for a fuel injected engine with O2 sensors. I’m sure it could work, but I don’t think the computer would like the numbers it would be seeing. Might even Jack up the sensors.
I wonder if a small amount could be used in a mower without issue
