LiON riding machines can go an acre, even more. The battery packs are huge. LiON tech is red hot now. Improvements in utility and safety prove inevitable. Even a silicon battery may arise. Elderly "snow bird' types hate the noise and effluents from gas machines. Legal issues inevitably will also arise. DIY'ers like that the new machines simply start and work: No idiot throttle control, somehow, to juggle--to get right. Even encasing nuclear waste to serve as batteries is already here!: Pacemakers.

The forest service has standard (FS5100-1D) for Spark Arresters and 36 CFR 261.52 is the federal regulation that requires the use of spark arrestors in accordance with FS5100-1. Modifying the exhaust to improve performance is always a balance between flow restriction and performance. Just don’t get caught in the forest service jurisdiction without them. Painful and costly potential experience.

[@markdavis7586]

Your video was super. You were right on the money about users lugging their engines and clogging spark arrestors. I am a certified Stihl Service Technician and I can tell you for a fact that our shop and Stihl have never, ever refused a warranty repair based upon the type of oil used. Stihl will Double your warranty if you buy a six pack of Stihl HP Ultra oil at the time of purchase. I get a lot of units in for repair with bad gas. Also, I'm sure most owners are running 87 octane gas in their units. Stihl recommends at least 89 octane. So between owners not running the machine properly and using bad/wrong fuel, most of the spark arrestor problems can be credited to this. I would probably have a heart attack if just one of my customers said," Yes, I read the manual " You know us men, we don't read manuals!!! Removing the trimmer head shroud and running longer line in the trimmer is the biggest culprit too. These small engines will not run up to full song even if the trimmer line is just 1 inch too long (800 rpm decrease). As a final note I prefer Amsoil Sabre oil. You can use less and there is less smoke (more complete combustion) and it last a long time in the can. Thanks, Keep rockin' Mark D.

[@gatoryak7332]

"Stihl will double your warranty if you buy a six pack of Stihl HP Ultra oil at the time of purchase." That's exactly how my local dealer presented the proposition to me.

[@treesawyer5921]

👍 I agree. A propane torch does work very well. In fact any torch style lighter, such as a torch style cigar or grill lighter will get the screen red hot, which will burn off the carbon/crud. No scraping necessary.

Great advice! And thanks for asking; I'll add a note about my experience LOL. Long story short, after one season, I thought my KM56 powerhead was dead - either would not start or would stall with the slightest amount of throttle. After checking fuel, filter and plug, I pulled the spark arrestor screen. It had turned into an exhaust arrestor - packed solid! Propane torch did the trick. And sure enough, I used to run at midthrottle settings as opposed to wide open throttle. Fast forward; I've added a KM111 to the stable since we have two properties to deal with, and normallly run both it and the 56 at WOT or idle, nothing in between other than for delicate areas. I have not had to clean the screens on either of them for seven years. Love your channel!

[@xtalvt]

WOW ... funny to find this! I have a 37 year old Echo trimmer (SRM-210AE .. 1985) ...still runs great. I do run it rich (too much oil). Sure enough, about 5 years ago it would not start. Took off the muffler ... found the spark arrestor .... clogged solid. Cleaned it (eventually replaced it when I found one) ... still working great!

[@johnmaus4408]

Another way to improve the performance is to clean with upper cylinder cleaner. Allow to soak. Safe for carbs, 4 cycle and 2 cycle. If you want to really jump the performance then remove that screen. Drill a couple of holes 1/4 inch in the muffler. This reduces the back pressure in the cylinder which allows the half burned exhaust to exit the cylinder which is replaced by air with a higher fuel content. You will see huge jump in performance. EPA nazi, chill. We burn billions of gallons of gas on mowing huge lawns and on vacation and unnecessary travel and motor sports. We as a society are just making noise and doing rhe same thing anyway.

[@pineappleboi27]

Glad I watched the whole thing. I've had 0 problems with most of our Stihl equipment while using Stihl oil, but that's probably because we use them commercially, at full throttle for most of the day. This is useful information because our least used tool, our hedge cutter, always seems to be preforming lackluster.

[@em4703]

I switched to Motul 800 offroad and never looked back. The HP Ultra is a great oil, but I love the smell and less deposits that the motul puts on the table.

Very rarely ever replaced the spark arrestor unless damaged. Get the handheld torch out and burn screen until cherry red, blow out with air, and if its still clogged spray screen with penetrating oil and reburn it. It will clean up after that.

Great video! I just helped a buddy of mine fix his Stihl BP blower with the same issue in the same manner.... quick & free fix. The advice about running wide open throttle (WOT) I'd spot on for at least a good part of the time. As a former 2 stroke dirt bike rider and racer for years, the advice is the same. To have better and more complete combustion with an oil/gas mixture WOT once in awhile is a must. The smaller the engine the more true this is otherwise expect clogged up spark arrester screens. I've run stihl, husky and homelite 2 stroke power equipment for 45 years and never had this problem, just mix the right ratio and stay away from ethanol/bad gas & don't forget to clean the airfilter once in awhile.

Great videos! A few words about 2 cycle engines.. The cold seizure is when a piston expands unevenly and scores usually on the exhaust side. The cause is starting a 2 cycle engine and running it at full throttle from the start. The cure is to warm up the engine at idle for a short time before going full throttle.

[@johnnellis3025]

How long do you let a 2 cycle eng. warm up?

[@B4TS1]

@@johnnellis3025 How I do it, in the summer idle for about 10 seconds then half throttle for another 20. Chain saws in the winter should be warmed up too before cutting at full throttle. Same for 2 cycle snow blowers. I have 2 cycle engines over 10 years old and never had a problem with piston wear.

[@shawndubay4050]

I usually start the engine on whatever two stroke equipment that I'm going to work with then lite a Marlboro red short up. When I'm done with my smoke I let it rip and hear the power of a stihl as I get it done. I have equipment going on 10 plus years old. I don't constantly hold the throttle wide open the whole time I'm working but it stays between half on easy tasks and three quarters to full on the thicker or harder stuff. No sense in running a powerful trimmer wide open throttle just to trim between one to three inches off of grass. Now if it's a foot and a half or more of grass and mess then it's wide open and slicing through but that's a pretty good load for it to handle.

[@AM-dn4lk]

After a long time of trouble shooting, I did recognise this exhaust filter/flame arrestor was 100% clogged. I took it out many years ago and all is well. I have had no sparks emitting from the exhaust. My take on it is, if you have such a screen filter regardless of your RPM or oil used, it is just a matter of time and it will get clogged. I use light body SAE automotive oil and no problem. My FS55 is about 20 years old now, but works well, with very good power and acceleration. I don't use the unit often, but when I do, I push the unit long and hard. Thank you Chickanic for highlighting this problem and fix.

The motorcycle industry is where to look for the correct 2 stroke info. We have been running clean burning oil for decades that promote reliability and performance. When someone says "no you can't run your machine without the spark arrestor " then winks at you, they really mean the opposite. Spark arrestor are mandatory for motorcycle racing on state and federal property. We always cut the screens out and replace it with a cotter pin so when tech inspection sticks a probe in the exhaust it stops at the cotter pin. Passes tech every time.

the only time you shouldnt run a machine at full throttle is when you're trimmin around delicate things otherwise always run it full throttle

[@Steelologist]

Great video and 100% true. Another thing worth mentioning is incorrect gas/oil mix ratio. Many people buy these tools which are designed to run on 2% mix (AKA 50:1) and start using 40:1 or sometimes even 30:1because they "provide better lubrication". This, of course, is not true, but what is true is that those super oil rich ratios will help clog up the screens even faster. KZbin is full of "experts" recommending 40:1 to improve longevity even though the Stihl manual says not to do that even if the saw/trimmer/blower... are brand new. But who needs those boring manuals when we have self proclaimed mechanics who know better, right?

I have used Stihl equipment for nearly 25 years - string trimmers, hedge clippers (HS80), edger (FC85), hand blower (BG86), and chain saw (limited use). I have gone through many string trimmers - FS85, FS94r, as well as BG86. Cleaning out the exhaust screen and port is just routine maintenance. There is nothing unique in this task. For the last 20 years, I've used Amsoil, at about 50:1. The FC85 has ran for more than 15 years. But the trimmers run for 2-4 years - engines lock up. The advise of running WOT is important. I think it may be the key to the FC85 longevity. Edging is always WOT (also use it with a 22" hedge clipper attachment). I used my FS94r to trim out 5-7 lawns per day. Many of the comments here speak about "2 cycle." Many of the Stihl family are 4 cycle. The issue is not 2 or 4 cycle, rather the lubrication mechanism - sump vs. vapor. My trimmers have been 4 cycle for years and I have no problem. One valve adjustment after about 50 hours and never again. The major problem is carb diaphragm failures. Apparently, the ethanol degrades them. A rebuild is simple. Even new ones are not very expensive.

[@rightsideofthegrass8114]

@@btolich I don't know where to buy ethanol-free gasoline. I do buy Premium grade gas for all Stihl gear. Is it better than Regular? Dunno ... I have no statistics to prove one way or another. Many years ago, somebody on a Forum strongly encouraged the hand-held equipment to burn Premium.

[@btolich]

@@rightsideofthegrass8114 Bummer! Even though you're using premium grade, it still has ethanol, and that degrades the rubber components of the small engines. The octane rating merely has to do with how much compression the fuel can withstand before detonation. Premium is typically used in vehicles with high compression ratios. Small engines don't generally have high enough compression ratios to warrant the use of premium fuel.

Yeah, I've had a lawn and landscape maintenance business for over 30 years, and I noticed that problem years ago on my Stihl stuff, but I never had anyone ever tell me it should be run at full throttle to avoid it. And I rarely run at full throttle, for the noise if nothing else. I've always used just enough power with string trimmers and edgers, etc, to get the job done.

I've been into non ethanol gas at the filling station as well as Tru Fuel for a dozen years. If I'm within 100' of an electrical outlet I will reflexively grab my 12-amp corded trimmer. It never fails at anything. At any rate, I've learned a lot from this channel and recommend it highly.

I was a Silver Certified Stihl Tech for 4.5 yrs. Number one cause of problems is fuel. I always told everyone for the $11 buy the pack of Stihl oil (silver bottle) that doubles your warranty, but then take it and throw it away. The orange bottle of non synthetic stihl oil caused way less problems and would run with more power. Ive argued with people about this but the non synthetic Stihl oil is much better than the synthetic. The silver bottle mixed with gas will disintegrate much quicker as well.

Thanks for this. I'm new at this and was afraid running the new trimmer wide open would wear on it too hard. Turns out the opposite is true. The wait list at the local dealer is weeks long so the better I can learn to take care of it myself, the better off it'll be.

[@toddfranklin63]

Yeah, but know when to say when. Don't void your warranty by going too far.

[@branfrog]

I just picked up a fs91R, the strange thing is the manual actually says: do not run on full open throttle during the break-in period (until about the third tank of fuel); and the trimmer will reach “full power” performance at about the 3-5th tank of fuel. Also as mentioned in the video, I was able to extend my warranty by 2 years by buying the 6-pack of oil with my trimmer, so people would definitely be using sthil oil during this break on period. After watching this, it’s a recipe for getting the spark arrester clogged. 🤷‍♂️ At least we know how to unclog it I guess.

It would be interesting to see and independent lab test the Echo, Stihl, Amsoil and others mentioned to see exactly which is the best. I have several Stihl products and have used Stihl oil in all of them and have never had an issue, probably because I read the manual and followed the dealer's advice.. Maybe your customers' Stihl products would have had the same problem with other branded oils if not running the trimmer at the higher RPMs. Stihl doubles the warranty if you purchase the 6 pack of Stihl oil when purchasing your tool/machine.
