As a last resort check the coil-flywheel gap. I had something that was too far and no spark.

this carb looks nothin like that
tho i said "no m", it's lookin like mtronic after some searchin
it's been to a well known stihler b4
"scored jug" he was told, they didnt test it
jug looks good to me thru plug hole
"would run fer bout 10 min, quit as if switch was shut off
start when cooled off" - owner
i havent tryed to restart after pullin plug right after it quit, lookin fer sparks
ran good til instant quit @ wfo cut

carb looks like bottom - 9, 10

There was/is updated fuel filter carb solenoid for those.
You can tell by the filter and solenoid color,,
The kit was like $15 bux a year ago.
Google the no spark,261 c m mtronic it is fussy fer spark,, computer kinda controls it.
Keep us posted

Older thread but has info

I paid $15 for the kit bout 2 yrs ago. USA was bout $75 for same kit, its in the thread above.


From that thread
I fixed a MS241 today that had an unreliable idle and was hard to start hot with white solenoid and the new fuel filter. Runs like a new saw now. It’s an awesome little saw.

Color coded fuel filters? Stihl can fuck off with all that stupid shit.
