    Anyone own a newer stihl with the computer controlled fuel system?

    Been looking hard at a MS362 CM.
    Still a little Leary of the no carb, selinoid controlled fuel system.

    STIHL M-Tronic™ engine management system. With STIHL M-Tronic™, an onboard microprocessor digitally monitors and automatically compensates for changes in your work conditions including elevation, temperature, fuel quality, varying octane levels and dirty air filters.

    It's a pro series chainsaw.
    My last one is at 15 years old with weekly use. Time to put it in backup saw duty and get a new one.

    That's a great saw. No need to be leary, M-tronic has been out for over 5 years now. Fuel injected saws are just around the corner, the first model will be in US dealers this year. One of Stihl's cut-off machines is fuel injected and has been out for a few years now.

    My newest saw is a 261 with a standard carb. Once my 440 dies, it will be replaced by a carbed/ported 461 or 462.

    Most of the builders like them but I staying old school as long as possible. The only model I know of with issues is the 661, I think they are up to version 3 on the software just to help those models. If you do buy a new one, get it from a well known local dealer so if you need the warranty, it will be easy.

    As for the 362, I'm pretty sure the 400 will be replacing it soon but make sure you get the newest gen 2 saw which is a little lighter.

    The 500i is the fuel injected saw, the specs so far on it seems to be a killer saw but who knows when it will be on the shelves.

    Going to look at a lightly used 20" ms 362 carb model tonight. I'll inspect the piston via exhaust port for any signs of overheating.
    Aside from bar/chain/sprocket condition and overall condition, anything I should inspect on it?
    Any easy tests I can do to verify condition without actually cutting wood?

    That’s the saw that I wanted to buy, decided to go a cheaper route and got a 271 instead. When I was researching the m tronic seems like a solid system, and with all the epa regulation now there’s not a lot of adjustment in the new carb saws.

    I had a 271 for years and it was a great saw. Loaned it to a coworker last year and it was stolen. Just came across a nice MS361 at a pawn shop and finally have a larger saw again. Just used it to cut up some decent oak branches that fell recently and it is a beast. I’m used to my little echo cs3000 trim saw.

    Pulling the muffler is the best way to check the p&c, second would be a compression test. I would look for an aftermarket p&c, need to pull the top cover and recoil off to check that those are OEM Stihl.

    JP8819 is correct, lot of clones out there. If it looks cheap, walk away.

    The carb screws have limiter tabs to keep them from turning so much, pull those off and you are good to tune as needed.

    20190112_123434.jpg 20190112_123547.jpg Bucked some 24" sweetgum today with the new Ms362 20" bar.
    Skip chain cuts really fast.
    Big upgrade from my MS250.

    The Ms250 feels like a toy after cutting with the 362.
    Not sure I could run it safely for more than a couple hours, its heavy.
    Once I get tired, I stop.
    Respect the buzzsaw.

    That’s a great acquisition on a commercial grade saw. Nice score!

    Noticed some fine sawdust in the carb box that shouldn't be there.

    Apparently the 362 air filter is known for not seating well, basically leaking.
    Multiple reports of commercial use saws losing lower ends due to dirt/dust contamination.
    Stihl has an upgraded air filter to minimize it.
    Hopefully I can find one online.
    Cant help but scratch my head though.
    Should not need to worry about an air filter!

    That said, the saw cuts amazingly.

    I now have 4 stihl saws that all take a different sized file. I made a roll out file pouch labeled with each size file.
    I'll find a way to mix them up eventually!
    The MS390 needs a new sprocket, bar and chain. I may replace the bar and chain with a Oregon #72 that uses a 3/16" file just to keep things common.

    Bad logistics on my part.

    017 5/32"
    MS390 7/32"
    MS250 3/16"
    MS362 13/64"

    Maybe cracker patch a seal with some mold release and rtv? Generously apply mold release around the sealing areas, apply a small bead of rtv and then install filter. Let dry and hope for the best!

    @346ci

    Any thoughts or recommendations on saw "safety" gloves? I want a pair just for cutting, not as a general work glove.

    Anti vibration/kevlar.

    Been eyeballing these:
    51dI7r59D2L._AC_SY400_.jpg
    Description
    The Forester Hi-Vis Arborist Rope & Climbing Glove cannot be beaten! The glove is lined with Dupont Kevlar to meet ANSI Cut Level 4 Standards. The anti-slip palm and will grip better when wet! This glove also is built with impact protection on the back to help provide extra protection from smash and impact hazards.

    Features & details
    • ANSI Cut Level 4
    • Impact Resistant
    • Anti Slip Palm
    • Hi-Vis Color
    • Extreme Breathable

    I received the kevlar anti vibration gloves. Well made, great value for $20, in my opinion.
    If you run saws, trimmers, power tools etc, grab a pair. I'm going to buy another set to rotate out.
    They are not high dexterity, but running a chainsaw doesn't require it.
    The thickness and padding are nice.
