Hello IceBlossom ... I am another 820 lover-hater. Your bobbin addition is an interesting twist that I just may give a try. Another way I have worked through things is by threading from spool through hole in the plastic next to the right of it. (See photo in link below.) Then upwards to the thread guide. Then over to the machine.
You might try repositioning your spool onto the centre of the three spool holders. The one you are currently using, is not intended for stitching mode, but solely for when you are refilling the bobbins. For me, when not winding bobbins I hang a small pin cushion off it or have an extra spool of thread in place.
There's a lot of detail here that may help everyone ....... and explains the spool holders more clearly.

So far I have just skimmed through and want to go back for a better read.
Looks like there is a lot of useful info there.
