Janome 6600P making "tock tock" noise
Sewing fine. Haven't hit anything. Cleaned bobbin case and under it. Put a drop of oil on wick. Changed the needle. Seems I've had this happen before & some combination of the above made it stop. Ideas? Oh yeah, I tried a different bobbin too & they are Janome bobbins.
I have a class next Saturday. If I take it in for servicing I doubt I'll have it back in time.
