i opened a new carto this evening.... Added the juice in the proper way... Wating between adding until i was sure the filler was saturated with juice.... did a blow out of the excess not too much just enough to omit the bits in the center and now... the juice tastes burnt... not good at all... Wondering if I did something wrong or am I missing a step.....

Setup is Ego-t.....
510 LR (1.5 ohm) Dual Coil Cartomizers
Cola flavor juice at 16mg

Any info you got would be great....
