550xp in the workshop

They are not to bad once you have done a few , the stop/choke still catches me out sometimes though.

Check the state of the piston, do all the normal things you would on a non AT saw as they often are the things that fail on AT saws. You can spray carb cleaner down the carb and see if it will fire but would do the compression and piston check before going too far.
No reset button on the carb, the saw should fuel and flood if you pull it over on full choke a few times. Check the gauze filter and metering arm, same as on a normal carb - they aren't that different!

Spud my 550 is playing up, well when I say playing up it runs fine but won’t tick over can you te set the AT ?

You can put it back to factory settings and update the software, however this may not help the idling issue, any lack of compression and the first thing to go is the idle, there is a sort of mod you can do if all else fails.

There is a firmware upgrade to help earlier saws which richens the low speed setting but you can't just change the idle as on a conventional saw. I have had a few in like this and sorted them so just drop me a line if you want a bit of help.
