So what is the solution?? I'm certain I'm not the first to see that and won't be the last! I'm thinking of trying to modify that bearing surface/operating rod arrangement with epoxy and a brass bushing. Cut a slot so the operating rod can set into the brass bushing, then first open the plastic and epoxy in the bushing .. rotate it (the slot) just a bit to where the rod an get into the bushing but normal operation won't have it pop out. If other saws  use that arraignment there is going to be a need for a solution within a year or so is my guess.

My bet is those saws in an area were its sandy or have other "abrasive" contaminants...they are going to fail fast.. might be what happened here. I told the customer to sell it while it still has value and find some older MS290's for me to build if he likes that class of saw!

I'm not going to be the guy who gets this out there....I'll leave that to someone in the Stihl community. I'll try to be a solution if possible.

Post a pic of the holder and linkage. I think you are on the right track with some kind of bushing. A small cable thimble was what I was thinking the other day. A farm/ranch saw is just that.

Might tell the owner to look into getting/trading for a pro class saw if he's going to log with it.  These were not meant for this kind of use to start with.  Sad to say, there getting cheaper made everyday and not limited to just Stihl either.

I don't know the Stihl line very well. What current "pro level" saws can he trade into that won't have that style throttle linkage/assembly? All of them? Or are there ones to avoid there as well. Certainly don't want to point him into another more expensive option that has the same issue. He has a 460 that's fairly fresh also a 660, so it has to be something like the 362...assuming it has a better arrangement.

If he's got a 460 and a 660, I don't know why he would want another smaller one unless its for limbing.  The 460 is about all I would think he would need mostly.  Had loggers in my timber this fall and they mostly used 461's.  They had a 660 there but never had to use it.  As far as the linkage goes, sounds like that is something he could look into himself, or you could tag along with him.  Don't know much about the newer ones either, but I would hope they would be made better than that.

The 391 and the 362 use the same carb bracket the are both part of the 1140 series saws. The 261 shares a similar style setup. A 441 uses a throttle cable. If it where mine i would put a new carb bracket on and run it. If i remember the carb bracket is not real expensive. From the 362 i had worked on.

video deleted. Think I'll get the plastic and get it running and convince him to sell that saw. No. Not interested in another set up like that. I'll stock some plastic, maybe build a brass fix to the issue for stubborn customers. My bet is Stihl will eventually address the issue making this a temporary situation.
