Just the usual checks for leaks but you will need to set the mixture again. A good starting point is to screw the mixture screw right in then screw it back 1 1/2 turns, get the engine running and warm then turn the mixture screw in until the engine note changes and turn the screw back out 1/4 of a turn. A good check to see if you've got it right is to pull the choke out while it's warm and running, if the engine speeds up then it's too weak, if it falters then it's too rich, if it stays the same or speeds up slightly then it's OK.
Go for a good run then check one of the spark plugs, it should be a nice biscuit colour, if it's black and sooty then the mixture is too rich. Try it and take a picture so we can see.
