271 has always been a stratto saw, uses same piston as the 261 just a farm ranch clamshell. Odds are his mtronic issue was a 40$ solenoid too about 90% of the time that’s all it is. People always want to blame the mtronic for their issues but lots of times it’s something else. Kinda like pulling the efi off your car to put on a 2bbl carb.
I can't recall how old it is. 5 years would be a qualified guess.
It’s dead simple and you don’t need the mdg1 to fix and mtronic saw most of the time, I use mine to scan hours most of the time unless it’s 500i. Mtronic and autotune work very well and yes they do increase performance. Most guys porting saws say the mtronic version will beat the non mtronic version simply because it’s tuning in the cut all the time. The old black solenoids wore out because of fuel contaminants because of no hardened seat. They made the green to replace the bad design black one and all the newer saws have a white one. The white and green have a hardened seat for the fuel metering assembly and give very little problem if you change the 5$ orange fuel filter once a year. And you act like it’s hard to work on or something, still just a carb and I can change a Stihl solenoid in about 15 minutes on the tailgate of a truck. Like I said buy 50-60$ in parts do a reset and I will bet the saw will run fine. And if it doesn’t odds are it’s not the mtronics problem and you have an air leak or something else wrong that will still be wrong with regular carb.
It’s new enough to be a white solenoid so when you put that in do your reset and it will be fine I bet. And weather you think it needs a filter or not put a new orange one in once a year. I have 2 green and 2 white solenoids in my shop as spares for any saw I’m working on for the tree services
White is it.
Please find me the strato ports on this cylinder.
Your right i was thinking of a he 311/362
Yes all the same used to be white or black but green became the universal replacement for the black ones
It gos into the side of the carb and adjusts fuel flow by restricting a port in carb just takes the place of the jet. Stihl solenoids are replaceable and as far as what I’ve been told is husky requires you to buy the whole carb that’s 125-175 ish depending where it’s bought.
Agreed... for me, the occasional cutter, i love the fact i dont have to worry about tuning the saws, (thats coming from a stihl tech who has to fiddle with carb screws on a daily basis while working on saws and trimmers) i just fire em up and let em warm up for a few min wihile pulling on the gloves and other ppe, and just go to work cutting, knowing its gonna run right... i tend to lean towards my 261cm, 280c (first gen mtronic that still had manual low speed and idle adjustments) and my ms661cm, over the ms362 (non mtronic) or 044, because it always feels like they need a retune every time i run em...LOL
That 270/280 was an odd duck saw and the self tuning carb with an adjustable low and idle was weird. Can’t remember what the official name of that one was. Mtronic came a year or so later on the ms 441 as the official first fully self tuning Stihl.
As stated earlier, I have no problem with progress, but this just brings very little benefit, if any at all, to anyone with basic understanding of how an engine works.
If your regular carb saws need a re-tune, every time you run them, something isn't right.
