Mine back fires also nothing wrong with it. Even when it is warmedup you might still hear one backfire every now and then but like the above persons have stated it is normal and the rotary engine is 4 stroke not 2.

rotary, 4 'stroke', intake, compression, combustion/power, exhaust. 4. count them.
not 2 cycles doing things in parallel per 'combustion chamber', like a 2 stroke:
the crankcase is not pressurised in a rotary engine during the exhaust 'stroke' then turned into a vacuum to draw in air/fuel for the next pressurization. They are quite different, though similar in concept (2 strokes are relatively valve-less other than the reed valve, which not all have anyways)
the rotary engine is not a 2 stroke, write it on the chalkboard 100 times.
