Enjoying your candle as much as possible starts with great candle care and maintenance. It may seem like a pain to upkeep your candle but if you don't your candle will still burn but not as you want, or should expect. Take the time to keep up your candle and it will pay off.
Keeping your candle's wick trimmed to 1/4 of an inch at all times and only burning your candle in 4 hour increments helps control the amount of wax that is present; keeping the amount of wax controlled the carbon is absorbed by the flame. This means less soot is formed while the candle is burning and that means a cleaner burning candle for you
Your candle is not sitting straight or is in a drafty area. For safety sake & the sake of proper burn, always burn candles well away from drafts, other heat sources, and anything flammable, also make sure your candle is on a level surface.
A candle smoking after blowing it out it completely normal but to prevent that from happening you should dip your wick (yep, that's what it's called). What that means is, while your flame is still lit, use a poker (wick dipper or old butter knife) and simply flick your wick downwards into your liquid wax and allow the wick to flick back up, it will be extinguish right away with little to no smoke. It will also be easier to light next time as it will now be coated with a bit of wax. You could also use a candle snuffer.
Your candle is tunneling. With all candles , the first burn is the most important. Candles should burn for one hour for every inch of diameter of the candle. If you're not into measuring, pay attention to where the wax pools before you extinguish your candle. It should touch the container or reach the edges of your jar. If the wax is not allowed to liquefy it will create a tunnel. this is especially important the first time you light your candle. Once a candle tunnels, it will continue to burn that way for the life of the candle, thus falling short of burn time promised.
