Hello all, new to the forum and hoping to get some help with this Pfaff 145 H3 BLN I just picked up. To my admittedly very untrained eye it seems like it is timed ok, but the top thread snags a bit as the hook brings it around, causing a clicking noise. It seems to sew ok but I assume this snag/noise isn't normal — any ideas what would cause this? Thanks
