201 not starting hot

[Westphalian]

Well try a new Solenoid then it's cheap enough and good to have anyway.

am I right in saying that my non mtronic version does not have a solenoid valve?

You stated on 1st post you had ms201 “CM”
That tells us that is was a mtronic by your description of cm at end
But you have standard carb version. So it is a “ms201” only
No reset or solenoid on your saw.

it's not mtronic

Mine is the Top handle, M-Tronic model.

Because it's the Rear handle model, I don't think it would have same issue as the Top handles.

Vapor lock occurs when the carb gets hot enough to boil the fuel in it. It all depends on how close the carb is to the jug and how the overall airflow is across the cylinder. How much swarf do you have under the recoil cover? One thing I do is I blow my saws off every time I use them, especially under the recoil. Saw looks to be kind of filthy so I'm curious and e-gas mix tends to boil more easily. Only time my saws look like that is when I'm done using them, before they go back to the shop to get cleaned off with a blow gun and rags.

Sorry, it was to differentiate it from the top handle version
