But what about the fuel tank breather? If you are sucking out fuel, you need to let air in otherwise the saw exhibits running out of fuel symptoms.

It will look like this....pull it off and you should be able to suck air through it relatively easily. If it has sealed up, it needs replacing.

Tank vent Genuine Stihl Part OEM Part No. 0000 350 5802 Suitable for the following Stihl Machines: MS 201, MS 201 C...

 

I'll check it but in my experience it only comes into use once the saw has been drinking a bit of fuel and this saw plays up within seconds of starting.

Probably right but desperate men do desperate things worth trying as if this goes on much longer, it will be like triggers brush!!

Did the plug get swapped out? I had an MS200t with a loose centre electrode once and it was a bit like yours. Stick with NGK or Bosch!

Not yet, I usually do a swap early on because plugs fail in strange ways but a it is smaller than other plugs I have and I neglected to order it with other parts it didn't get done.

I've just had a look at the replacement piston and cylinder L&S sent em and it's the exact same problem. So now I have 2 wrong pistons... I'll have to call them tomorrow to see how they can fix this.

You could build a twin cylinder saw...look on the positives!

It's probably you, have you thought ? You might have the wrong chainsaw.😆

The real question is, in line, or V?

Nope, checked, double checked and then checked again.

MS201 carb in bits. Air leak on the hi circuit. Hi jet (check valve) and accel piston removed. Hi jet is fine, accel piston seal is smaller than the piston (see piccy 2) and looking a bit shabby. That'll be it then. Apparently you cant buy a replacement accel piston assy from Stihl though..... Just needs a new O ring seal really.

I think you will find it is the same as the MS200T...pretty sure of that!
