Upper movable blade broke and a local repairman said the lower blade is off by 1/8 inch and cannot be adjusted. Sound correct? Not a babylock dealer. An old machine but don't really have the money for a new one when only use it occasionally and for serging seams after sewing them, even though I'm sure it does lots more.
I think I would get another opinion. Sometimes you run across lazy technicians or those who would like to talk you into buying a new machine. Of course, if your machine is older, it could be difficult to locate replacement parts, but getting that info from another technician will confirm the first opinion.
SOURCE: Machine not sewing
If you have the machine threaded correctly, and are absolutely sure. New needles installed and it still does not sew, you most definitely have a timing problem. You should take to a qualified service center to be properly timed.

Sounds like a tension issue.
Check your tension units and thread guides are clean and free of lint....a rag moistened with methylated spirit (denatured, surgical etc) run between the disks will help.
Normal factory tension setting = 3 for all dials although resetting this style of tension unit is, frankly, awkward, so if it ends up being other than 3, don't worry too much, just write it down somewhere handy.
Start with all at tension 3 and try using 4 different colours of thread and sew a scrap to see the balance of the tensions to more easily locate any that are loose.
Ideally, the 2 needle threads should appear as secure dots not at all "loopy", while the looper threads should meet neatly at the edge and be a firm join without pulling at the edge on one side or the other.
Get the needle threads right first, then small adjustments to balance the looper threads....after a few adjustments you will probably have it back to normal.

What do you mean you are unable to pull the bobbin thread through, elaboration would help solve the problem...
I suspect I'm having the same problem with you if it's anything to do with the top thread looping around in the bobbin holder.
Damn machine!

Sounds like a tension problem. Your machine should have two tension adjusters. One for each needle. The book that came with your machine will tell you how. Another possibility is a bent needle.
