    Its not good to say "They are still 4-Mix". Makes it a vage, inaccurate and confusing as there are blowers with all types, regular two strokes, strato two strokes, 4-strokes, 4mix... Mot so easy to talk about these things anymore as its not many that is the same.

    Husqvarna had an accessory called "Skorsten", Chimney is eng word I think. It was a tube from muffler to a pipe you had attached in back of belt so exoust fumes were lead the same direction your farts went as you bend to cut tree. No exoust to inhale. Great in deep snow!

    Its not just falling branches as tree start to move. Its many reasons. Barberchair! Broken trunks etc Stump jumping butts. Tree moving unexpected as it start to go. Stump surfers that send trunk 10m behind stump. The shift in weight can get stump to crack, break or as I found out ones, even explode. There is many reasons... There is nothing you can do then as you could not do before it starts to go. Standing there when cutting will result in injury in some way sooner or later. Its not just hardwood as I had experience of. Its all felling. Not just me saying it its all fallers here. Education, certificates, forrest companys etc.. All try to teach this. Not standing there saved my life a couple times, Of this I am dead certain. I promise you if you stand there running saw as it goes and it pinches, your eyes is not up. Neither if is not so good place it stands and you need to see were you put feet...

    This series saw I always thought was a bit overpriced. I am stuck in the way we thought of saw models in the past. Not so much focus on brand, more focus on each model regardless of brand. You get a limited amount of runtime in the different classes. Sorted in to; Consumer grade, Homeowner, Farmer/semipro and pro. These were homeowner grade saws by runtime, design and performance but priced as a semipro. Lots of trouble and issues for the money they cost. There was others in this class that easily out performed them for same money.

    Silvadavid. If you are still here... I think the brand is not you issue, rather lack of experience, knowledge, good dealer and support.. Most of the stuff you mention is box store or internet shopping issues that you would not see buying from a dealer worth the name. Dealer cover up the loss in knowledge and experience when it comes to product choice and service. Regardless of brand a good dealer is priceless. The good dealers might not have the shiniest store, but I bet you know when you have one! Internet is a big place I am sure you will find your spot eventually.

    I don't know if it would work, but I suspect it would up to 45 degrees. A quick look in manual would perhaps tell for sure. There is different sizes on blowers. Largest handheld is likely just as good as the smaller back pack. But if I was to choose tool for a work that takes some time I rather have back pack blower on than carry the hand held. There is a lot of hand held sold to homeowners. Back packers are mostly for pro's that run a bit more and longer. There is quite a bit difference in the huff and puff in them between models so a try before purchase is not bad.

    I am not too familiar with the blowers, but I know there is. I don't see why it could not be tilted and upright again and still run. But run it on its side I doubt would be a bright idea. Most running backpack blower tend to stand, atleast those I have seen running them And the 20min a year I run mine... The trimmers I see here once in a while. Some from Stiga, some from Honda. They work ok. Its a good engine for this purpose.

    Not well at all, but in some machines you only operate in one position. Trimmers, back pack blowers as example.

    Thanks, Stig. Mick. There is two types of four strokes in hand held stuff. Those that is called four mix and have oil in fuel are more common and are used mostly by Stihl at this point in time Others have it as well, but don't sell as many. The consumer grade four stroke saws from east is also this type. Then there is pure four stroke engines with sump pump and hole kit! Most common is a engine built by Honda that Stiga and others had/have. Valve systems vary a bit as well

    You are joking, but some is turned in to two stroke, some hydraulic, transmission or other oils. Recycled oils is very common. We called it "Washed oils" earlier, now its pretty much standard.

    I doubt oil is the larger culprit in this drama. Fuels properties and composition is likely the larger factor combined with the manufacturing, recycling etc Emissions is not so much whats burnt, rather whats not and that is a bigger problem in a two stroke high reving engine. There is oils that are very good but the temps variations are no easy nut to crack. In most other engines the temp is easily controlled with cooling systems that let it heat up fast and stay within a short specific temp range. Aircooled temp range is much wider and harder to control in a saw for example. The principals behind the engine types is pretty fixed, like laws of nature. A two stroke flushed engine has few moving parts and low weight for the power it produce.

    Yes, a bit over the top for most I guess.. Point is that environmentally correct products actually is worse for environment as he will need two or three for same job during a specific time. Environmental impact from scratch to sale of one saw is way worse than from the sale and its use. Building saw, making parts, transports, recycling etc is way worse on environment than the fuel is digest in its lifetime! Here we have so good environmental rules so we can't build battery's for the products we make here. They need to be made in country's with less restrictions and environmental laws. Same go for a lot of things. I am crazy, I know that.. But this environmental stuff is way worse than most rational thinking...

    No, not much heavier. There is consumer grade fourstroke chainsaws on market now. China stuff I suspect. Haven't really looked in to it. I tested the Dolmar 500V. A four stroke 50cc. If it really is emissions they are after, a conventional two stroke engine With a good ignition system and fuel injection would be better than four stoke or stratified engines from a environmental point of view. Take a load of saws built in a country with not so hard restrictions on anything. Perhaps with not so great deal for workers as well. Built there dirt cheap. Waste and factory stuff is put behind shop or in closest river. Saw gets assembled from parts made there in factory if it can't be built else were cheaper. Then put the saws in boxes on a plane, fly this half way around the world or more to a warehouse were it is to be distributed. Some of these saws get sold locally, but most will get another plane ride to next ware house. There they sit until customer go in a store/web or real and store/dealer order it for him. Perhaps one more plane ride or truck ride to dealer. Transport from dealer is not all that bad, he get his grocery's and pick up the kids from school at the same time anyway as gas is pricey for him. During the life of this saw for this logger he runs 5l gas 300 day's a year. If he is lucky he'll run it a year, 1500 liters fuel go thru this emission correct saw. He rebuild it once as it ran too hot. After this year the saw need new crank and dealer tell him its cheaper to get a new one. So another saw go out dealers door. He pick up the Kids, do the shopping for this week, run by the hamburger place as he is a tiny bit pressed for time. Inside there is a little can were he put a dollar for the ones (in a well known country for making cheap stuff) that has it very ruff as their parents died from being exposed to chemicals and bad environment. Next weak the saw go kaboom in forrest and after a trip to dealer he get another on warranty. Dealer toss the saw in bin or send it to brand headquarters were it enjoy a plane ride and a few truck rides on the way. As the logger go to his work next day wit h his third new saw within 14 months he start thinking of the good old day's when he ran a saw 20-30 months and it was made an hours drive from his place. He even had two cousins and a uncle working there. But yes. His saw is environmentally correct and EPA put their sticker on it...

    The idea with contact surface like this is not bad, but it has its downsides. The contact can get bad even if its clean from erosion or corrosion. A thin layer of oil will do the trick to!

    The kill circuit is a grounding of coil. It has no switch. This system has been used on many other saws thru the years. It could be you don't get contact between cable on lever and plate on air filter bracket. I changed a few coils on newer HVA saws as the circuit inside coil is busted. But its more common with contact and cables.

    This is what we have been waiting for. Electronically controlled injector instead of carb. This and a conventional engine would be great! This is the future! I have no doubt.

    Accracy was very bad. You could tell rpm was high or low, I was more precise in my ears then app was. Its no good to use if you wish to know in any accuracy under 5000rpm. I bet most can hear rpm better than these apps.

    Dealers are often told what to say and think even. Brands teach them what to say if product fail. Often its operator or fuel, settings was popular to put blame on until they removed setting screws. Now they find something else to blame. Lean running saws is saws that run hot from not enough fuel. It can be caused by air leaks that affect pressures, but that is under piston ring. What happen above piston ring with pressures rarely case fails. I am no brand dealer and self taught. If they go on about stuff as they do with those that are depending on their product, I just sit and listen. Sort thru the BS and sometimes get a comment or question I respond to as short as I can. I could help and do sometimes. They bring the stuff here when it takes more than ten minuets to figure out and fix. They rarely ask what is done, just pay and go back to store.

    Loosing compression is not like a air leak. You still have lubrication and correct fuel mix. It will loose power and could have bad idle. I did this a few times. It feels hollow and sounds different. Put it to wood and its powerless. The 357 and most non X-torq saws with decomp at side has a tiny hole in cylinder wall about as high as it can get. Hole leads to a chamber were valve sit. The xtorq has decomp valve in top of expansion chamber in a big hole and no channel or hole to lead to valve. Perhaps this is same on the Stihls? Don't see so much Stihls here. I don't see how a broken valve can cause seizure. It would be very easy to know something is wrong and stop running. I guess anything is possible but you really have put some effort to it. On the saws were hole valve go in compression chamber it still will not happen much to it as flame will not eat material as it expand. If it did we would not have aluminum combustion surfaces as there is on piston and cylinder. The only thing coated/sleeved is were piston travel to reduce wear. The rest is exposed. Oil used could cause carbon buildup, corrosion etc, but thats not common today. When I see broken decomp valves its mostly broken from outside forces. A few had worn out spring, but I have never seen a engine blow up from a decomp valve yet.
