441c won't start when warm

[Wood Doctor]

I just got an MS 441 C into the shop that had a "whopping" 74 psi compression. Looks like it's been straight gassed. Good condition otherwise, cosmetically it looks almost new and not a thing wrong with it. I figure it's worth a top-end rebuild. Two years ago I did this with a Stihl MS 362 C that suffered from the same symptoms, and it's running today. That engine even had a cracked cylinder.

This repair kit is not valid for the MS 441. You have to replace the valve with the same one 0000 120 5110.

Additional information:
Previous valve 0000 120 5110 will be/or is already replaced by new one 0000 120 5111.

As mentioned by DND9000, 0000-120-5111 seems now to be the “new normal”.
I ordered a 0000-120-5110 and got the green one instead.
Was there a TI issued I am not aware off?

You didn`t miss anything. The green one is the new standart and it has replaced the older black one. That`s all, just simple.

Thank you

I rebuilt that 441 C M-tronic I mentioned in past #21 with a new top end and some other reconditioning. Not easy to do, but it runs flawlessly today. I like it.

If you change the solenoid, don't forget to change the fuel pickup filter for the orange one!
