Stihl MS441C
« on: September 30, 2014, 09:15:18 am »
Just got a new 441, read somewhere that I might have to do something to it. Choke it and let it run for 90 seconds plus then turn it off to reset something? Is there any truth in this or what? Suppose to have better response etc...

Thanks.

Go out and use it to drop some big 24" dia trees and block up the trunks with it.  That's all you gotta do.

That is for a reset calibration.  No bar and leave on the start position and then just switch it off. It may need that after a few tanks or might not.

Thanks, I'll keep that in mind. Man does it run good, can't wait till it gets broke in a little.

You only have to do that reset when you replace part of the CM system.
I had to replace a fuel solenoid last week on a MS362 CM and had to reset it.

Is the fuel "solenoid" the unit mounted to the carb?  On the 261cm I just pulled apart it looks as though it's more of a variable flow valve? Appears to be a coiled ribbon of stainless steel inside the "solenoid"    is it strictly on/off or variable????

Carb solenoid may be shot. Try the prime and pull with trigger held.

It had finally started after all the pulling.   Going to dump his mix for alook and go through it. Then check again. Thats what the other guys said solenoid might be going.  But will see next round.

Both the stihls that came in was this way too. Even the 026.  It might be the choke in air filter. But tore it all apart and dont see where its that bad. IMO still a stupid set up IMO.
Going to pull carb etc for a look too. Says it takes 20 pulls on it. It seems to too till fuel gets to it. So might be that or stiff diaphragm.  Who knows, time will tell.

Saving mustangmikes info = They likely ran the 441 low on fuel and kept trying to start it and it went into "rich protective mode" like it does for an air leak. Hold the throttle all the way open and pull the rope, I'll bet it will start.

Unless you can get it "re set", it will take a several tanks of fuel to fix itself.

stihl reset per MM

The dealer can do a reset that you can not do yourself (a few know how to do it).

If the saw runs, you can do a reset yourself. On that version I believe you leave it on Start for 90 seconds, then shut it off, then start it in Run and leave it for 90 seconds, then shut it off, then cut some big wood.

What did you do to get it running? If it was just flooded (someone used Start position when the saw was warm) I would not re set it, it should just work itself out. Even with a carbed saw, if someone floods it, they can be very hard to start, same difference!

Glad to hear it is running, the hard part is over!
