Re: motor will not continue to run.
Could be any of a number of things:
belts could be worn or stretched and need to be replaced - the belts can look fine but can be stretched causing the machine to run sporadically
if the motor has carbon brushes they may need to be replaced
foot control may have a short or other issue that is causing the short spurts of stitching
You indicate that something is "binding up". What, exactly, do you mean by this? If you mean that the bobbin case does not rotate, the timing of the machine may be off.
A good repair technician can diagnose what's happening and many do not charge (or charge a very minimal fee) to look at and diagnose machine issues. For a small/or no investment you can find out what's wrong and determine if it is worth the cost to fix.
Hope these ideas help.

have you checked 1.to make sure it's plugged into the wall outlet good? make sure the power & foot pedal are connected correctly to the machine? 2.does the motor smell in any way? when was the last time it was serviced?
hi, it could be several things
MACHINE DOES NOT RUN
1.the motor belt is probably broken
2.the motor belt may be loose-needs to be serviced
MOTOR DOES NOT RUN
1.the electrical cord may be defective-replace
2.the motor maybe burned out-smell the motor to see if it smells like a dirty pair of socks, if the motor smells it needs to be repalced
3.the foot pedal may be defective-replace
The motor is running.That is confirmed that motor is fine.But the wires from motor has to be checked.the motor connections are getting short and this is causing the plastic belt to burn.Check the motor as well as its connection.
Have you been oiling the bearings per the guide? Try to isolate the upper mechanism versus the lower by rocking the handwheel and observing which causes the bind (take the bobbin and needle thread off to prevent jamming). You may have to remove some of the covers to see most of it. As long as no gearing becomes shifted or uncoupled, you should not cause trouble. Try taking the motor belt off to see if the motor itself may be binding. Good to see people keeping old, but still working machines running
well that is very nice idea you can fix with your self provide talls most commonly use.Set of screw driver,open and socket wrench,pliers etc...Remove the top cover plate by loosening bolt holding the cover and cover besides the handwheel where the motor was installed besure it was unplug from ac source(No power)Check the motor holder that attaching from casing.You can see the motor coupled by the belt.In the motor holder there is a bolt slot adjustment for tensioning belt tighning and loosening.If you want to disconnect the belt and replaced loosen the tension and pull out the belt.Sometime belt are sliping to the pulley it affect
the sewing machine operation,you can tighten from adjusting the tension of the belt.adjust not so tight after adjusting try to run manually first by turning handwheel freely if the motor will run freely with out obtruction no power supply.If your satiesfied try to run with power supply but jag twice first to be sure no problem occured before continous operation.
1. Hopefully the motor belt came off in transit (I have seen this several times), this is easy to fix after you remove the covers. Unfortunately the covers are not easy to remove. But if you can then just put the belt back on.
2. If the hand wheel is stiff then it is a jam or bind. Jams are always in the hook area, binds can be in several different parts which only a technician can help.
The belt material in the bottom of the machine is there because the belt is slipping and wearing away because of the 'stiffness' this "stiffness" is also causing the motor to strain. If you continue to use the machine in it's current state the motor WILL burn out.
Could be caused by one or two problems or both.
Lack of lubrication oil/grease on all bearings in particular the handwheel bearing, this will be the "tune up" your dealer did.
Other cause could be thread that has somehow got wrapped round the handwheel shaft.
Unless you know how to get into the top of the machine and lubricate it yourself then it is back to the dealer. Same access to the machine is needed to check for trapped thread.
If you do take it to the dealer make him/her show you how to lubricate the thing yourself.
Best of luck
