[SD/Modeling] Need Help making a particle horizontal or a horizontal version of this

[jonathan ross]

I am trying to make a plague fire bat like unit and while this effect works for the flame, I cant get it to be horizontal, I managed to attach to a unit models bone which made it horizontal but facing the opposite way (toward the units back not forward). Would love if Someone could rotate this so it goes either down, or toward the screen in the z axis. Or create one similar that would work as such. Also if you could teach me how to do it myself that would be even better, so i could do it in the future
