- In this video we will look at a customers Husqvarna T540 top handle chainsaw that won't start. This isn't going to be a fuel problem so we will look at some ignition diagnosis. #smallenginerepair

Great explanation! Duplicating it with the 550xp was pretty cool.
Thanks. I need to try it with the latest version of auto tune like a 592 and see what happens.
Great mechanic it takes patience and you have a lot of them. Love your videos.😊
Thanks for watching!
Nice diagnosis &repair. Sometimes it’s the simplest thing that is hardest to figure out. Laaaaater.
Thanks for watching!
Great content. I’ve had to sand different posts before. I’ve used the two methods you do. Loosen and close, and check using a meter to check ohms. Check between plates and jug. But easy to clean. A lot of great information.
Thanks!
Great video. I really like you doing the voice over. Thanks
Thanks for watching!
Excellent find! That would have stumped me and probably anyone who does not have the computer interface for it, some that do. I just made an entry into my biologic data bank too.
Ya I wonder how long it would have taken me to make the connection if it weren't for that green light.
Love watching your videos love the way you present them. Good job.
Thanks for watching!
Excellent work and very good info! Who knew it would burp with stop switch down! Stored in memory bank and I'm going to share this with my Husky dealer he may or may not know this! Already put carb stand to work and its awesome thanks so much! See ya next time!
Glad to hear you like the carb stand. Later.
Excellent video Scott, I’ll for sure try that with a Jonsered 2253 that didn’t connect to Service Hub!
Good luck. Thanks for watching!
Thanks Brother 😀 That Stop Switch Issue Has Not Crossed My Bench Yet But Now I Know if I Come Across It 😊😎 👍🏼👍🏼👍🏼👍🏼
It seems like an obvious solution now that I've seen it happen but its still kinda weird.
Excellent sleuthing my friend!
Thanks for watching!
Brilliant, Scott 👍👏
Later.
I love the vid bro, I think I'll stick to my old saws lol
Ya technology can be good and bad. Thanks for watching!
What an awesome find! Thanks for sharing your knowledge Scott!
And thank you for watching!
Great work Scott ☝️that was a tricky one for sure.
It sure was. Thanks for watching!
I think I'll leave the auto tune repairs to you Scott. 😉
I'm fine with that. Thanks for watching!
Hello there, scott! I have a Stihl FS90R trimmer, and since I run 40:1 mixed gas in all my saws now, I use the same mix for my trimmer, but the carb needs a little adjustment to compensate...how much do you think the high jet should be adjusted?
Thats a tough question. The difference between 40 and 50 to one is so slight that it may not even need adjustment depending on where it was set and the current temperature. Theres no such answer as "open it up 1/8 turn".
@@TheGreasyShopRag I asked because it was overheating and losing power, so I stopped using it, and ran the normal suite of tests...no air leaks, the piston/cylinder were fine, and the only thing I had changed was from 50:1 to 40:1...I adjusted the carb slightly today after I let it heat up. went 1/2 turn on the high jet, and 1/4 turn on the low speed jet. Seemed to run a lot better, and didn't overheat...so hopefully I didn't mess anything up...
@@albertkropp Sounds like you've got a handle on the situation.
@@TheGreasyShopRag Alright...so long story short adjusting the carb didn't fix the issue, and finally I went to my local dealer, and was told that my mix was the problem, because the newer engine designs need to run hotter to get full combustion, and what essentially happened was that the engine temp was lowered by my mix using more oil, and thus the rings got carbon seized...My question now is does this also apply to new chainsaw designs as well? I asked him, and he just adamantly told me 50:1 on everything, but I was under the impression that 40:1 was better for the longevity of the engine internals...
@@albertkropp Hmmm. That sounds more like a oil quality issue than an oil ratio issue. People everywhere are running 40:1 without issue. Now if you told me that you removed the grass shield I would believe that the engine is turning slower due to more line out. A slower engine won't get as hot and burn away carbon deposits.
That is snap on multimeter?
Yes. I had a fancier version with a color screen but it was useless in direct sunlight so I traded it in on the basic model.
Auto tune is not for anyone who wants to be self sufficient away from dealers and repair shops.
They are making it so you are dependent on them. That's not going to work for those who live in remote locations.
Agreed.
I notice the smaller repair guys starting to carry Echo and other basic tools now (the thing of tools coming back to them, where they need to sit near a laptop to repair or diagnose a tool scares them). As they're already maxed out on time as it is. I've listened to a few of the two-stroke engine mechanics over in U.S. who've brought the subject up too. What do they recommend nowadays as an upgrade pathway for professional timber folks. And they're scratching their head too, and starting to look to other brands. So in everything from the Mom and Pop up to the professional full time timber guy, it's starting to affect a lot of folks. And honestly AutoTune tools are new enough, that we still haven't established what strain it's going to put on the dealer and distributor infrastructure. I mean, the support infrastructure for two-stroke technology is not like that for motor vehicles.
There's a tree care and management company here, which grew out of a kind of tool hire origin or background, which ran teams of line workers, who supported the actual medium voltage utility power line repair crews (mostly doing tree management preventative maintenance). And that was always a fully Stihl shop for years. Even they've had it up to their tossils I've heard, and are looking beyond the normal two stroke engine brands, to find something else. I don't know what it may mean into the future. Just chatting to distribtors, repair people, arborists and line people, there's a good bit of concern around these days. I pay a slight bit of attention still to diesel big engine stuff like track machines, and it's been ramping up it's high tech too in it's own way. Not sure how it's going, but that area has changed too since when I first started work in my teens. Approaching forty years ago now.
The thing I'm worried at though, aside from tools and machines. Is just the basic labour and skills that go with that labour. And that seems to be the most dramatic change. The shortage of lots of skills. It's really across the spectrum.
