Cut the roast into 4-6 large chunks, removing any large pieces of fat.
Press saute on the Instant Pot. When hot, add the oil. Add half the meat chunks. Brown completely on all sides. Remove to a plate and brown the second half of the meat. Remove from the instant pot.
With the Instant Pot still on saute, add the onion and cook until it start to become translucent, about 3 minutes. Add the garlic, cumin, and oregano and cook an additional minute. Pour in the broth, chipotle chiles, lime juice, cider vinegar, salt, pepper, cloves and bay leaves. Stir to combine, then add the roast back into the Instant Pot.
Place the lid on the Instant Pot and lock. Select high pressure and cook for 60 minutes. When done, allow the pressure to release naturally. Once the pin has dropped, remove the lid, and using tongs remove the meat from the Instant Pot and place on a cutting board.
Using 2 forks, shredded the beef and return to the Instant Pot. Stir to coat the meat with leftover juices. Remove the bay leaves. Enjoy.
