MS201tc Won’t Idle. Easy fix

[@IndianaDoug]

There’s levels to this stuff. First, second first, and third first. Got it👍🏻

Stole it fair and square from I Do Cars here on YT

Who would have thought that a woodchip that big could be sucked up past the filter. Even not snapped down all the way. Nice catch Richard.

[@pennyless4tea]

Dang it lol. Give us a spoiler alert next time with a comment like this.😅 I’ll still watch it anyway.

Important information. Thanks for posting.

Something I've discovered on my small tools, 435 Husky and like, as I don't do a huge amount out doors in winter time in the past, and I just pounced on an opportunity to clear some vegetation this winter when other tasks were out of the way until next spring. I'm seeing for the first time the change in weather, how it affects how tools run (some auto tuned, and some manually carb adjusted). It was noticeable too on my smaller 30cc-ish brushcutter tools as well as small power saws (and larger 40 to 50cc brushcutter tools that I only use for heavy work, as they are so fuel hungry). The larger brushcutters, saws etc run okay, albeit different than in warm, less moist climates. I've gone to a barely 1 to 50 mix or less on the '435' small saw tool today, and mixed a special can just for it. As the other large tools and brushcutters I'm running 1 to 40, with decent performance. I just found that these smaller engines in colder winter find it harder to burn off the oil, . . . and given the climate in winter, the small 40cc or smaller two stroke engines seem to benefit from additional gasoline to them, . . especially in things such as low jet idle running. I mean, the loss in horsepower in both the small chain saw and brushcutter was job-smacking (as both are reliable tools in normal milder weather). I've started to purchase the ethanol free 1 to 50 pre-mixed cans of fuel at tool store, for the small brushcutter as it's the tool I use least in winter, but it gets regular and consistent use in summer to tidy lawn verges etc. Hence why I've as much time on that tools as I have.

[@academicmailbox7798]

I'd not do it ever with one of my pro tools, but today I became sufficiently curious about my small 435 saw, that I thinned the ethanol free fuel out more than 1 to 50, using some raw gasoline added, ending up at a dilution somewhere between 1 to 55 and 1 to 60. Just for one tank, and I processed a bit of fire wood using this fuel mix. It's something I'd never do, if it wasn't mid winter. And it struck me just how well the small 435 ran, when it received that little bit extra petrol. It's really the only tool where I can't depend on my auto tune to fix it. So I had to figure out something. I've been looking for a while at a rear handle 540 XP mark III. The reason I didn't obtain one, is the .325 chain I run on my small 435 suits me better. I run a top handle T540 a good bit now, it's an older one still running the mini 3/8 inch chain. And it has it's uses (the modern T540 has got a mini .325 inch chain, rather than the old mini 3/8 inch). It would be handy to have something like the build of the 550 XP, in a smaller saw (the 'plastic' handle bar of the 435 is nice because it's lightweight, but they do crack and break as the plastic handlebar isn't strong enough). The 540 XP is a strongly built tool, a metal handle bar etc, and it can operate both mini 3/8 and mini .325. The irony is, is that tools like the 435 can operate an 18 inch bar with full .325 chain stock, yet it's handle bar is flimsy.

[@academicmailbox7798]

I'd heard rave things from various saw users about the humble 435, and it was purely curiosity which made me acquire one to try. And further curiosity as to it's change in performance in colder weather, that drew my attention to fuel mixes (and finally, to add to this, it's the same behavior I've witnessed with perfectly good working small sized brush cutter engines). Yeah, my local dealer and repair shop are good to adjust these carb settings for me. But our winters are that brief and short in this part of the world, that normally I find myself ramping up work in springtime (at which time, my smallest tools and non auto tuned ones are usually back to working as expected). My dealer did persuade me to 'store' them this winter containing the ethanol free pre-mix fuel. Which I've done. In the past though, I've even got around that simply by switching on the tools once a fortnight and just warming them up, storing them on shelves in a control climate indoors etc. I've been lucky this past ten years, since taking up two stroke engine tools much more (yes, on my carpentry hand tools I've a lot of 18 volt stuff, and 110 volt stuff, . . and when one already has enough 'mess' of chargers and batteries created already from carpentry tools, . . it's unlikely that Husqvarna will ever persuade me to buy their electric motor tools). Although, the one place I could maybe justify that is for winter use power saws, to substitute for smaller two-stroke equipment. Only maybe. My solution of the thinner fuel mix today, for smaller two stroke equipment has me leaning in the direction of just mixing a dedicated gasoline richer can of fuel for smaller engines.

[@christopherlehman4045]

Lithium batteries don’t like cold very well and can loose up to half the capacity in cold weather. I personally wouldn’t lean out the oil amount in a saw for cold weather just tune the carb correctly for the temp. Stratto saws need all the oil they can for the bearings. I definitely wouldn’t go leaner than 50:1

[@academicmailbox7798]

Interesting, as I mentioned I was curious enough, it isn't a major important tool in my line up. But what I tend to discover, is what is going on with the 435, is an exaggerated version of what happens with the larger tools too. For example, I did a couple of hours use of an 85cc Husqvarna this morning early. And sure enough, I got on cut-out with that tool too. Something that never happens. We are close down to sea levels here, and my hunch is that barometric pressure does change a lot in these oceanic environments. A thing up in highland country might be thinner air. Someone suggested to me that colder air becomes more dense, and thus the additional gasoline provided by a slight carburettor adjustment can help out in this weather. The Husqvarna 435, a common enough tool in this part of the world (we're dealing with so much small wood and clearing bits of bushes, the oceanic climate means that low level ground scrublands expand rapidly, and hence brushcutters and these small portable saws get used a fair amount). The thing with a Husky 435, is it's impossible to get enough chain speed out of it, with a .325 inch pitch chain, to do any serious timber cutting. So it's a tool that's left to idle a lot, and handles 'scrubland' stuff where you don't fancy changing a brushcutter blade out to cut small stems. So the muffler spark arrestor mesh is going to become clogged and mine needs maintenance is my guess now. However, when one thinks about it, these lower powered small chainsaws that idle a lot, are the definition of a tool used in said scrubland, where you 100 percent want a spark arrestor mesh fitted to them. As I said, I probably used my 55 to 1 mix to at least blast some carbon away from the spark plug, if not the muffler too. But now, I think I've a better idea of how to maintain these smaller tools, that I only introduced to my set of tools this year. As I saw other guys using them. I'd be keen though to jump on to mini .325 chain, and a 540 XP saw soon. I think I'll be happier. That said, the top handle T540 and it's mini 3/8 inch bar, chain doesn't do what a 435 saw can. So having a rear handle 540 won't make much odd's. I think what I might need is a 565 saw, . . there are lots of times in scrub land clearance that one feels running a good 550 XP there, is just abuse of good machinery. And sometimes honestly for brush slashing a 60cc to 70cc with full 3/8 inch chain, is just the most hassle-free way to go. And deal with the weight one has to carry. These small saws, all of them, I've found things I like. I've found stuff that I don't.

[@mattw5729]

Good work thank you Sir.

[@discodiv8024]

I've had the same problem with mine ordered a new fuel pump solenoid waiting for it to be delivered. Carb sitting on the bench just went out and pulled that black shroud off and like the video some crap Jammed there.. will put it back together see how it goes.. but a big thank you sir..

That'll do it!

[@steveriggenbach90]

Great video. Got to remember look at the small stuff. The electronics can not adjust for no maintenance. Did you learn on your own, or by schooling? Combination?

[@richardflagg3084]

I went to the school of life. Lol! This is actually my second career. I was an Executive Chef for over 25 years if you can believe that. Anything you can find passion in, you can excel at.

[@7eis]

Have you replaced a lot of the white solenoids? I've gone through the carb, tank, breater, new filters, new plug, gapped coil. Had one recalibration but the thing died right after the throttle part at the end and wouldn't restart easily. I've ohm'd out the wires, checked full articulation of the butterflies. Flushed out every hose. It will start and run but occasionally bog and fall on it's face near idle. O ring from carb to filter housing is good too. Shits driving me crazy😂 literally ordered complete carb, solenoid, coil and fuel lines (buddy works at dealer and they let him return stuff)

[@richardflagg3084]

It's rare that a white solenoid fails. I've only replaced one and may have another on the bench in a couple of days. It's a new saw. Customer complaint is the same as a new saw 6 weeks ago. Good luck with the 201

[@richardflagg3084]

Silly question. Have you pressure and vacuum tested the saw?

[@chrischiampo7647]

That Looks Like a “German”Cockroach Wing Stuck in The Carb 😮😲😮Richard Maybe The Roach Hitched a Ride Too The USA in The Air Filter Box But Last Time The Saw Was Used He Was Sucked Past the Airfilter and Into The Saws Engine 😮😩😩😩😭😭 Poor Guy Came All The Way Here Only Too See The Afterlife When The Saw Hit 14,000RPM 😐😳😐
