Help with Janome 6600 dual feed
 

My dual feed mechanism on my janome 6600 will not click in when I try to engage it to the foot. Just flops down. I can still sew with it but need advice till I can take it in for service. Anyone have this problem

i had mine for several years but still had to fiddle with it sometimes when putting it back on.
it might be that yours is worn out.
could also be that it's being moody and you just have to keep starting over and trying again to get that little hook in place.
