Question about Juki MO-644D Mechanical Sewing Machine
Yes, needles are usually offset on sergers, one will be lower than the other.
You can download a manual from here: http://www.jukihome.com/products/mo644d.html its a pdf icon on left of screen, page 11 covers needles and the right needle is lower. It also says to change the right needle first, then the left one and to use a JL x 2 needle in the left side for heavy weight fabric.
Don't know with the Juki but I know my Bernette prefers the serger needles as they have a scarf/groove in the front as well as the back, ELX705, otherwise they are the same length as the standard domestic needle 130/705H.
Also, never unscrew the needle screw too far out, just enough to get the needles out and in, as there is sometimes a ballbearing up in the housing between the two needles and if you wind out the screws too far, this may drop out.
