201 fault diagnosis

[David Dobedoe]

201 top handle, starts easy, cuts well but often won't idle after its been started. Tends to settle down if i cut something.

Sometimes reving it up up seems to help.

It has a new air filter and plug recently.

What would be the next steps in sorting it?

 

(And yes I may well send it to Spud)

Is it an autotune?

[David Dobedoe]

Yes

[billpierce]

Id pull the carb. Clean it, replace diaphrams etc. If still no good possibly its the fuel solenoid.


Have revved the pants off it buried in some wood recently? Think this should get the autotune to recalibrate itself.

Flat out in big wood is Husqvarna reset, Stihl varies. Look in the manual but it goes something like cold start and leave ticking over for 30 seconds then rev it flat out till it picks up then tick over again. Takes about 90 seconds.

Just had a look at the reset instructions. Saw would need to run on 'cold start' for over 30 seconds. I'm lucky to get 10

Split impulse line ?

Bet its a dirty carb. We have 3, all periodically have the same issue.

Solenoid!

sounds like ours, a new fuel soleniod was fitted, ( easy enough to do ) works fine now. i talked to a technician about it and he said it was a very common fault.
