First of all - DON'T RESTRAIN HIM BY THE NECK! Doing so is just going to stress him out and keep him from getting comfortable with being handled. He's only two feet, so a bite from him now is a very, very small price to pay towards taming a wonderful pet (as you must know from your experiences thus far).
Generally speaking, young snakes are very nippy. In my opinion its completely understandable: being new to the world - everything is strange and unknown - and you don't know who/what to trust yet. Given time and regular handling he will come to know you as a 'non-threat'. Be sure to be diligent in handling him regularly, but not so often that it stresses him out (about every other day or so is plenty). Of course, after meals allow a couple extra days without handling so he can properly digest his food.
Be aware that snakes have decent short-term memory, but not-so-great long term memory (due to the phisiology of thier brains). This is very much why regular handling is so important.
Here are some basic things to also be mindful of for safe handling and keeping your burm 'tame':
* Be sure you and your hands do not smell like anything your snake may want to eat (i.e., mice, rats, rabbits, other mammals...). - always wash your hands before AND after handling your burm. Remember: a snake's sense of 'smell' is extraordinarily better than anything we humans can imagine.
* Be sure you are providing your pet with proper basic husbandry. If your pet is stressed from not being kept warm, or not having enough fresh water, or not having a hide box to feel 'safe' when he wants to - well, then your already moving in the wrong direction. A healthy, happy pet is the first step.
* Try to be sure the environment you handle him in does not contain any 'threats' that may be upsetting or exciting him. For example, smoke, scent of potential 'prey', loud noises (yes, snakes can hear - particularly only very low frequencies), or a lot of comotion or moving objects.
There may be other things I just can't think of right now (I'm exhausted from a long workout), but this should be a good start. Hopefully some of the more experienced keepers will post replies for you as well, as they are excellent sources of information/help.
Don't give up - your little burm can be a great pet in no time.
