If you are getting a lot of clogs, cut your tubIng with a fresh razor, nice and square. Avoid using scissors, as they will deform the end. This is very important inside your hotend, where the Bowden meets the the nozzle, in your heater block. Cut square, and insert firmly, until it bottoms out.
Also consider replacing your stock white Bowden fittings They aren't the best.
