Chainsaw Repair

So it sounds like the carb probably wasn’t adjusted correctly.  When the dealer replaced the choke and trigger (new trigger has two coke settings where I swear the old one only had one).  Wouldn’t they adjust the carb to make sure it was running correctly before giving it back to me?

And the instructions for lean failure is to change my fuel for the most part or switch to higher octane.  But it sounded like that isn’t the only fix.  Sounds like I need to rebuild the motor...
