Ms441c no spark, am I dumb?

[Stihlalltheway]

Been dickin around with an ms441c with no spark for far longer than I care to admit. Put a new coil, new plug, and cleaned every kind of connection on it. Nothing worked yet. Guy I got it from said the electronic carb is fried and that killed the ignition, I have no idea if that’s true or possible or how to test it. Any ideas?

Kill switch?

Kill switch?

Seems to be functioning fine

I believe that there's a solenoid that controls the M-tronic system, that if it goes nothing works.
If you want to part ways with it let me know.

Is the flywheel/coil gapped to exactly 0.008, NOT a business card? I had a 461 that didn't want to spark when I gapped it with business card, but it had spark when I gapped it to Stihl's fancy specs.

When I’m by the saw again I’ll grab a feeler gauge and try it.

I’m my experience if you don’t pull the crap out of it m-tronic saws show no spark. Be worth a shot to give it a good yank.

Correct
If you have a solenoid or wiring to it problem-no spark.
Solenoid should read about 75 ohms.
That's what my 441c reads.
Mtronic needs to see solenoid to spark.

Just for something to do once.
I disconnected the solenoid and fitted a 75ohm resistor-no go.

I found that out on a 193t. I tried using a drill to spin it while checking for spark, and got nothing until I put the starter cover on and pulled hard. The drill goes 1800rpm or so.

Stihl wants you to buy a special tool to check for a spark on any M-tronic saw like yours:


That's the way it is. I guess this is supposed to be scientific advancement.

I ordered a solenoid, if it doesn’t start after that it might get the sledgehammer

I feel your pain. When the 441cm runs, it's a good saw. Mine started on the second pull in the Start position. I buck cut a truckload of ash rounds, most of which needed noodle cutting in half or even quarters. I used a 25" bar. My full chisel chain was sharp and the saw never bogged down.

Just had the same issue with a 441, turned out to be a broken wire in the harness.

 

[Stihlalltheway]

New solenoid is in, coil gapped, pulled really really hard, nothing. Any other ideas before tannerite?

 

[Nutball]

Are you checking for spark with the spark plug out of the cylinder, but well grounded to the cylinder, so you can actually see the spark or lack of spark?

yes

Bad flywheel? Very rare, but it happens…

Pictures?

Look over all the connectors real close. Check fir pins that have been pushed out or pins of a different(dark) color. Find a way to clean the pins if you find them. See if you can find someone close with the scan tool (MDG-1) and that could be a help.
