Need help determining if this 201TC is M-Tronic or not?

[brul-ler]

I have just replaced a defective solenoid valve on my Stihl ms 201 c-m. It took about 5 minutes including 90 seconds reset

 

[brul-ler]

My Stihl ms 201 c-m has gone dead again, lastly replaced solenoid valve-filter-tank breather valve-spark plug-membranes in carburettor. It starts fine, but when used in logs it dies after about 10-20 seconds,,? however, can be started again immediately and dies again after 10-20 seconds..What to do? just ordered a new ignition coil but don't know if that's the problem?? Etc. Erik

Check the wiring harness for continuity and inspect for any worn spots that could ground out. It certainly could be the coil though. A video of it doing this could maybe help.

The screen in the carb could be plugged

OP can you do a compression test?

 

[stihltech]

How about the tank vent?

The cut out in the engine housing by the coil with plastic insert is m-tronic only.

Found a black wire with no connection and pulled a new brown one to solder together with black,,"don't feel like taking the whole saw apart to replace the wiring harness" also had the ignition coil replaced,,so if it doesn't run properly I'll throw it away in the lake..best New Year greetings Erik the lazy electrician.

Well run it with the old coil first with the wire repaired so we know what it was if its fixed

I think that might be the kill wire. Move the switch to the off position and check for continuity.

I keep the old ignition coil as a spare and expect it to be ok, wiring faults were only measured when the new one was installed, it seemed like a crap job to replace the coil. It will be exciting to test drive it when the repair is over. Best regards Erik

I measured from the marked areas on the wire and there was no connection, the "kill switc" is not located near the measuring area..

Hope I can make it work, as I have just bought a practice stack of beech wood in the state forest..

 

[Stihl Learning]

I hope you have a bigger saw! lol

 

[brul-ler]

The small but fantastic 201er can easily fix it, it has done that several times before, but of course has our big brother, an 18-year-old Stihl 026..

Then my favorite saw works again, it was not a wiring fault "the black wire with no connection was for the kill switch. Found an old stump from a fallen tree and tested without it stalling. the conclusion: bad ignition coil..Best regards and Happy newyear. Erik

Do you think that maybe you should acknowledge my earlier post?

you were right that it was black wire for kill wire and it had nothing to do with the actual problem. thanks for the information..

My two favorite saws do an excellent job even with a good size stack. The new ignition coil on the Ms 201c-m has solved the problem of stalling...
