I never had the problem with ethanol fuels that most seem to have. Or have had. Only issues I really had were fuel lines. And plastic fuel tanks on older atv's. I used to work on them. It seemed to eat a layer off the inside of them early on and ran sludge into the carbs.Question for the saw guys, Since the government had been adding ethanol to our gas almost all my small engine carbs have been ruined. I have replaced the carbs on most of them and now empty they tank and run them until they are out of fuel before putting them away. I notice that my saw's (3 Stihl's) dont seem to have a problem and I dont empty them out. Is it the 2 stoke oil that keeps the fuel from turning to crap ?
Every little thing you can do to help those 2 strokes along will pay off down the road. For fuel I run non-ethanol.Question for the saw guys, Since the government had been adding ethanol to our gas almost all my small engine carbs have been ruined.

Ethanol is hard on rubber. It also will leave a brown deposit behind when it evaporates/vaporizes that usually/eventually will cause an issue. By running an engine dry, you may not really be helping as it leaves the residual fuel behind to vaporize and attach to even more fuel components.Question for the saw guys, Since the government had been adding ethanol to our gas almost all my small engine carbs have been ruined.

Good to know about the stabil. I've used their products in the past, but not that one. All my ope has ran better since running seafoam through them on occasion.Ethanol is hard on rubber.

Non-ethanol fuel if you can find it is the answer. If it isn’t readily available, buy Sta-Bil 360 Marine and use it according to the label. It neutralizes the alcohol and prevents fuel vapor from leaving deposits. It was developed for carbureted boats because they tend to be greatly affected with no easy to get Efree fuel at marinas.
In my previous business I used a lot of small engine fuel and I never had a fuel related issue after beginning to use 360 Marine….I used it for years. I use it today in my ZT and ATV but I do buy Efree for 2cycles (just too easy since it is readily available).
The product is available at WM, either in the auto section or the boat section.

Those hoses on the fuel jugs are vinyl I believe.Good to know about the stabil. I've used their products in the past, but not that one. All my ope has ran better since running seafoam through them on occasion.
Funny thing about the E free fuel, in my area anyway. I use vp fuel jugs. I got a blue one to dedicate to the E free fuel and the nozzle got so hard and stiff I thought it was going to snap. All my other jugs that I used for regular gas and diesel were fine and I'd had them for several years. I figured if the E free fuel was doing that to the nozzle on my jug, it couldn't be doing my fuel lines any favors. Long story short, I quit buying it. In the summer months I turn my fuel over pretty quick anyway.
This may not be the right place for this question, but here goes…
The contractor working on my house has this nifty tool for removing nails. Anyone know what it is and where you can find them?
The guys who know say that it is one of the few oils safe at 50:1 in a chainsaw. I still have been running it at 32:1 and have no issue with splooge or carbon on the muffler and my plugs are very clean.Like @Lawless and after watching some saw repair videos, I recently switched to Red Armor for mix. I have probably burned several gallons of saw gas with the new 2 cycle oil now, and it seems to work well.
I Never did use the Ultra, even though the dealer tried to sell me on it. I was just used to , or was, to blue/green fuel.
I also run a richer oil mix, 32-40:1 instead of 50:1. I figure in the Eastern WA heat and dust a little extra oil helps. Have done this for years.
All I ever ran was the stihl orange bottle, then came the hp ultra, never liked that stuff. Then I learned about modding saws and dropped it like a bad habit. Since then I've ran red armor, belray h1r, and now motul 800 offroad. All 50:1. I used to follow a faller on youtube that built saws. He's cut over a million board feet on his og ms462 build and it's still going strong. Mix ratio ? 800 offroad at 50:1.The guys who know say that it is one of the few oils safe at 50:1 in a chainsaw.

This was my first try when I first started having problems, but I still had problems when using sta-bil . My problem is that some 2 strokes I only use once a year. I have had the best luck just empty out the tank then idle until they run out of fuel.Ethanol is hard on rubber.

Lol.I run ethanol free gas in all my two strokes. Also use it in my boat motors. Local marine shop said they do not sell or recommend Sta-
Bil fuel stabilizer. Told me it causes more problems in boat motors than it solves. Their recommendation is to use Star Tron in the fuel.
The shop does sell only Star Tron. Figure he can sell any and all brands he wants and make the same amount of $ on any of them. All he said is that Sta-bil didn't work as advertised in his experience. I think they all work about they same, if you use them, and I have used both.Lol.
Did they sell Star Tron?
If they sold both they would tell you both work but that the more expensive one was better.
My son uses bottled fule in his chainsaw for now but since he purchased land that needs a ton of clearing my guess is he will learn to mix a good batch on his own.
I ran 2 stoke outboards for many years. It was more expensive but they were tuned to run on premium.
Ocassionally staybill was added from November till March not to say they were not ran during those months, just less than 2 days a week.
No automatic oilers in any of them.
I would run my larger one at 4500 rpm or at idle and not much between.
Not exactly a hot rod chainsaw but started every time. I rebuilt carbs about every 10 years, probably because I got hold of bad gas.
Anyway a question for the experts.
Why do people not run premium in thier saws?
An old story comes to mind:Lol.

Ive got the same. Is there enough of us now to be the 261 master race?Driving by ACE today and caved. I've got a big day of cutting/splitting tomorrow.

Maybe we can get Tbac to make a muffler for the 261?Ive got the same. Is there enough of us now to be the 261 master race?
Generally they do exhaust ports and different air filters not mufflers. More like asking for a muzzle brake.Maybe we can get Tbac to make a muffler for the 261?
I've got his air filter and the three point dawgs on my 462. And I built a knockoff of his bark box. It sounded beefy but I had mixed feelings about the flat front cover on the muffler. Seemed like the saw ran hotter. Now I use a modified version the chainsaw guys buckshot cover. Two pieces of ⅝" tubing, ½" id, put of the front of the cover.Generally they do exhaust ports and different air filters not mufflers. More like asking for a muzzle brake.
Don't have any of their stuff yet. If you've watched any of Guilty of Treeson stuff and seen Gordy it's his company.![]()

I would go over here and read or ask questions.Had a pretty serious day of cutting yesterday, I'm having mixed feelings after a day of the 261c. Looking around online and it seems like the 261c has problems at high altitude. I'm talking 9k-10k ft. Would start for the first time then if it ever stopped, it wouldn't start for another 45min +/-.
Sounds like the self adjusting carb has problems with extremes like that. One person said to let it run high idle for quite a while before starting the day.
Any other input or ideas would be appreciated.
It is always the recommended procedure to let a Mtronic saw idle for about 10-15 seconds before shutting them down. This lets the carb sort of set itself back away from WOT. Doing this helps to not have restarting issues.Had a pretty serious day of cutting yesterday, I'm having mixed feelings after a day of the 261c.

Did a quick search and found this. Haven't done it myself but should work.

Others have already mentioned it but I would do a reset on it. I've only had two mtronic saws and both have ran like scalded dogs and neither have given me issues. 441cm and a 462cm.Had a pretty serious day of cutting yesterday, I'm having mixed feelings after a day of the 261c.

Never noticed that on either of mine.Just be aware that if you reset, it’ll take a few tanks of fuel before it gets back to full power.
If you investigate, you find tons of saw mechanics and builders who have seen it ruin saws. It was developed to use in 4mix (4 cycle) equipment to keep the valves clean. It does not meet the current 2 cycle oil spec and in fact is a few behind.I’m curious why some are against this oil?
Got a mouth full more than I'd like to admit!I've had old school saws vapor lock. Try loosening the fuel cap to relieve pressure.
Besides that what are your credentials that would make you believable?I clear land for a living, clear cuts for farming, about 60 acres a year. I run six saws 2 Husky 395 Husky 365 3 Sthils 261 241 242 I have been doing this for 46 years. I run about 6 gallons week through them, I normally use one of the bigger saws to buck up, and cut down and the smaller saws to limb out. I cut down a days worth of trees, about 60 to 75, pull them out into the field to be limbed out, then skidded over and bucked up into logs, pallet wood and firewood. I cut about 2 tri-axle loads of wood a day. I mention this to give my statement some credibility. I use cheap 87 octane with alcohol, I use Prestone two cycle out board oil mix bought at Walmart. If you read any of the the oil mixes sold by the saw manufactures the all say their oil is made by others. As best as I can tell Husky oil is made by Prestone and just re bottled. I figure as a rule of thumb to put a little over a 1000 gallons of gas through a saw before it is worn out. I have over the years tried different mixes, high test and different grades and different mixing oils. This combination of oil, I would guess I am probably about a 45 to one mix on the oil and have been using the last 12 years to work the best. Most of the time when I lose a saw, I have run it over, crunched it with a tree in the woods or landing when a log rolls over on it, every mistake you can make I have managed more than once. I have only had motors go in two saws out of the last 20 or so saws. When they are worn out by me, they are pretty much whipped all around and not worth rebuilding. I rotate saws, making sure none of them sits too long, as a rule I go to work with 4 saws every day, one is always in the log truck.
It’s an Alkylate fuel, I know that and that part is good if you can afford it. Most folks cutting at least firewood can’t afford it so not a lot of empirical data.Because my Stihl saw and weed whacker are my “Precious” I only use the Stihl ready mix gas in them. Probably $30/gallon if I did the math. Certainly not for commercial ops just hobbyist homeowners like me.
What’s the word on the Stihl fuel.
My weed wacker gets biweekly use this time of year. Still maybe I use a quart through the summer.It’s an Alkylate fuel, I know that and that part is good if you can afford it. Most folks cutting at least firewood can’t afford it so not a lot of empirical data.
Sound like you're using girl math.My weed wacker gets biweekly use this time of year. Still maybe I use a quart through the summer.
The saw gets less frequent use. Only when the odd storm knocks a tree down and I want some ambiance wood to burn.
If between the two if I burn a gallon a year I would be surprised.
That said I find every time I’m at Ace and the cashier tells me “Your $0.50 short of a $5.00 coupon” I end up picking up a $30 can of Stihl gas to hit the limit.
See me for financial tips.
