Plus, I'd be surprised if a shop told you it was fixed without testing it themselves or gave it back to you knowing it still didn't work right.
All those things you explained that they did is them hunting for the problem.
They should have tested it and it should have worked for them to charge you and give it back to you. They might have ran it on a stand but that is no where near a true test because they are only testing the motor without a load. You take it up north where it is not the same temperature and/or elevation and the problem is back.
Here's what I would do:
Find out how they tested it to make sure it was OK when it left the shop. Grill them. They charged you.
Polaris is known for making motors just lean enough to run right. That's mostly the reason why they are having problems with motors now with all the EPA regulations out there. This is also why a shop won't start messing with carb settings outside of factory specs. They don't want to be held liable if it burns down.
