Hi guys I just wanted to Introduce to you my other Channel "Things to Know" - which i'm just getting started. It's a go-to channel for insightful worldly explanations, handy tips, and expert advice on everyday things and repairs of domestic items. Here is the link: th-cam.com/channels/O8P9x5kUZ44Fb11vanLFsg.html
I mentioned this before, " if only I saw your videos years ago". Much of what you explained I learned either by spending hours or making costly mistakes. I enjoy your detailed explanations & diagrams even on topics that I am reasonably good at. Best I can do is to always full view, comment and .👍to help channel growth with YT algorithm. Stay well, Joe Z
Phenomenal!! Thank you so much. I run about a dozen chain saws for tree work, but I've never REALLY understood the how & why of carburetion. And I sure wish all those years ago I had had teachers who could teach like you do! Thanks again!
You are a master of these machines, I am truly grateful for sharing your knowledge with all of us,Thank you sir, for your generosity. God bless you always.
Apologies to @TheRepairSpecialist if the following already exists but I'd LOVE a video detailing how&why a powerhead may "get quirky" IF it's tuned well & running well but then, in my case, you're running it (echo 590) very hard in the midday FL humid heat, working your way through a large Oak trunk, and then like 20 or 40min into the job you find yourself needing to adjust the carb to re-gain that good-running condition you'd previously had! Currently giving myself a "remedial carb's course" because of that problem right now, I stored my 590 directly after the described scenario and a few months later upon trying to use it, it's barely turning-over (fuel quality / spark / etc, all 'low hanging fruits' were inspected before looking to the carb of this ~1yr old, well-maintained 590!) Hope you figured out your SRM's scenario/solution, nothing more frustrating than taking care of your unit, self-schooling yourself, and still fighting to keep it working and/or contemplating simply buying a 2nd unit ("I WOULD have a 'parts saw' if I just bought a 2nd 590!", lol!!)
Maybe I was having a parallel saw problem last summer bucking a large trunk after felling it. I was using one of my favs - a 372XP and in the hot weather it started bogging down on me losing power. I still don't know why it happened and it's been running just fine since! (In my case I didn't try a carb adjustment but simply switched to a bigger saw. I tend to take quite a few saws on jobs so when I run into problems I can just switch saws and keep working.)
I recently bought a Stihl MS 661 CM Magnum by accident (complicated story so I'll spare everyone the details) and I'm pretty pissed off because I wanted the MS 661 R instead! My reasoning is that I don't like the idea of having electronics in a chainsaw. My question is for those that have the CM, What is your experience with your saw and has the electronics caused you any problems. I'm thinking of getting rid of it or possibly giving it a chance. UPDATE: Since I got this saw a few days ago today was really the first chance I got to test this saw out. I cut a lot of ash from 24" to over 30" dia. Between how easy this saw starts and its cutting power it won me over. This saw is an animal that screams for more wood should you slow down below its cutting speed. Am now happy with it and thank you to everyone that took time out to respond.
no the electronics work very well, our 261 and 241 run very well with the electronic carburettor, even our MS500i works very well after months of no operation.
give it a chance. electronic battery chainsaw just takes too long to charge up, and when the battery aged, the battery life will be shorter. fuel engine is easy and reliable.
You're singin' my song re computers in saws. I've tried to stick with the "3 series" in the Husky line just to avoid electronics - 346xp, 372xp, 390xp and I've been given a couple in the 5 series but the work horses are the 3s. (FYI, I switched to the T450iP for climbing and love it over my 4 gas climbing saws. Can't say enough about that effective efficient tool...)
because the person adjusted the carburetor H and L needle clockwise to make the engine run lean, a lean engine cause more air intake and less fuel to burn, to give more power, but its not good for the engine, otherwise it will overheat, depend on the carburetor setting. i had a 2 stroke RC car and my engine blew because of too lean and overheated.
Hey, i bought a 2 stroke electric generator and i cleaned the carburetor. The guy demo-ed the generator more than once with ether because he could not be bothered to clean the carb. It is only running fine if i let the choke on. It is possible than a lack of filter make the fuel mixture run lean, or i should look somewhere else to find another air input ? Or a damaged piston than got higher resistance, seal ? It is seems to be able to run if I unhook the speed regulation and remove the choke at least for 10-15second.
the possibilities are, 1. is the filter clean? . 2. if the filter is damaged, replace a new one. yes even if the tube of the filter is damaged which will called "Air leak" that will drawn more air into the engine to make the fuel mixture lean. 3. be very sure that the carburetor filter is free of blockage. 4. it could be the carburetor need adjusted a little bit.
@@mitchelrichardson8164 thanks for the answer but i figured it out, I did not took apart the front panel when i wrote this. But here is the update: I took away the front panel, i discovered that the carburetor/motor joint was flipped on itself, creating a vaccum/air intake after the carburetor. So I cleaned the joint, made new one from cartboard envelope from Amazon (pen, cutter, and drill bit with drill in reverse running fast to make dust with the cartboard, on a piece of wood ). It was running and stable but the speed regulation part was getting stuck and the diy air filter need adjusting. So I did remove the filter to see if it was starving for air. And I put a some air around the regulator shaft and now it running like I want even with the filter on. Thanks, have a great day.

You put a ton of work in these videos with so much detail. You are one of the best on TH-cam my friend.
Wow. That is some of the best feedback I’ve had. Thank you. I really appreciate it. Craig
TOTALLY agree!

That was a great explanation, I run everything a tiny touch rich and they last forever
Phenomenal!! Thank you so much.

Thank you that awesome comment. I really appreciate it. Craig 👍👍👍👍
You make more sense than anyone else I have listened to. Thank you 🌞
Thank you 👍👍👍
Finally someone gave the perfect explanation behind this! Thank you very much!
Thank you for your awesome comment. I really appreciate it. Craig

Thanks for an excellent video Sir, very well made and informative 👍
Very enjoyable video, Knowledge is Power!!!
DAMNED BRILLIANT MECHANIC AND TECHNICIAN YOU ARE !!! MANY THANKS !!!! GREAT SERVICE YOUARE PROVIDING !!!

Thank you once again for a very informative video. Very helpful indeed.
Thank you so much also. Craig
Great information thank you Sir!
My pleasure! Thank you for your comment. Craig
Awesome video, well done ❗👌❗🔥❗💪❗
Thank you very much! 👍
❤ excellent advice 😊

Terima kasih atas penjelasannya
Explain please why enhine increase rpm when mixture is lean?
Yes, and I always thought that lean meant that there was too much air, not too much fuel. Silly me.
because the person adjusted the carburetor H and L needle clockwise to make the engine run lean, a lean engine cause more air intake and less fuel to burn, to give more power, but its not good for the engine, otherwise it will overheat, depend on the carburetor setting. i had a 2 stroke RC car and my engine blew because of too lean and overheated.
can a lean condition cause piston scores even if the gas to oil ration is correct?
yes, as the engine generates too much heat so the piston expands too much
nice
Thanks
Thanks
👍👍

Echo 225 srm run great for 20-30 minutes and then start to run rough and lost power

Oh, it might be a vacuum building up, i suspected something was up with fuel intake but not this way, you mentioned this into another video.

No air filter will cause it to be lean. Also a dirty carb will cause it to die after a period of time of revving it.
