Erratic idle, won't idle down as quick as it should, dies if picked too fast. Basically, what your saw is doing.
You are still under warranty? Wouldn't hurt to tote it to the dealer. That's the second advantage with buying new gear, first is..its new, second is, free warranty work. You paid for that.
Shaun: Haha! Try to fake out the saw...funny. I'll try that on my wife's cat sometime...not sure it'll work on my saw. You did mention something that caught my attention: One of your saws does this. What variety of saw do you have? Is it an M-Tronic?
I've got 3 of the 441mtronics, they're similar in age/hours and they all get used daily. Only one dies out when you pick it up, the other 2 are fine. I've tried the reset procedure, no difference. They all get fresh mix daily
...does it die if you give it throttle without picking the saw up? I watched your video and was hoping you would try something like. That would debunk my puddling fuel theory if the saw doesn't die from giving it throttle and possibly even eliminating the carb as even being an issue.
Working with repair shop here in Ireland,we have had one customer who has just returned his third 441 CM to us.All the above problems with the saws.First one just became unusable.Sent back to stihl who replaced carb.Customer refused to have it so they agreed to take back and gave him new one.This worked for three weeks before starting same symptoms and eventually would not stay running at all.We refused to work on it and sent it back.Same outcome.Third saw given but within ten gallons of fuel refused to start.Damaged piston and barrel we think.our opinion is that the saw was over revving.Stihl wont agree with us but took saw and sent to expert analysist.They have now supplied a fourth saw.Our customer refuses to take it and they are refusing to admit to us that these saws have a problem. Being unable to tune it we are reluctant to sell it either.We dont think the metering is correct for our climate and cant adjust.Stihl remain silent but am sure if nothing was wrong they would not be willing to replace so quick.We sell thirty oer so stihl saws most years,
Every Stihl carb I have replaced has come complete. I have no reason to believe that a C-M carb would be any different.Hey Memory,
My saw has been in for service twice for this issue. Dealer one couldn't recreate the problem. Dealer two recreated it and replaced the entire carb under warranty. That, however, still didn't fix the issue. From what others have said in this thread, there's a very very good chance the metering lever is set incorrectly (or is otherwise defective). Odd that I had two carbs with a maladjusted metering lever*, but that's what I'm going to ask the dealer to investigate when the saw goes back for it's third visit, which should be in the next week or so. I'll let you know what comes of the third hospital stay.
* = I wonder if a "carb replacement" is just replacing the carb core, and many (all?) "moving parts" from the old carb are scavenged and put on the new carb core--including the hosed metering lever. Dunno...anybody got a guess?
I run a 15" on my 576XPAT at times, who cares if his customers run a 13" bar, get the **** over to Ireland or in my backyard and see what we may be cutting that day.Ireland huh? Is your customer running a 13 inch guide bar on those MS 441 C-Ms?
Glad to see you don't know much about M-Tronic or AutoTune saws. Lean out test on MT/AT saws every second utilizing rpm as its main indicator, doesn't allow for over revving, regardless of bar length.Have your xpats been holding up to over revving?
