Where can i get needle clamp & screw for a Montgomery Ward " zigzag sewing machine" model no. UHT J1276, & need a needle clamp & screw ( part no. 7063) . Does this part have a universal p

The bobbin may be in backwards
the needle is not the correct one for the machine
the needle isn't correctly seated in the needle clamp
the machine is a little bit out of time.
Remember to hang on to the needle thread when you're trying to pick up the bobbin thread
Turn the handwheel in the direction that would advance the fabric from the front to the back of the machine
make sure the bobbin-winding spindle has been pushed back to the left for sewing
make sure your needle is inserted correctly as far as it will go with the flat side facing back
and that the upper tension disks of your machine are threaded correctly.
Make sure the presser foot is up when seating the thread through the upper tension.
Turn the hand wheel (TOWARDS YOU ONLY) never turn the hand wheel away from you and hold the needle thread lightly. .
pull the loop up and then pull both threads (top and bobbin) under the foot and toward the back of the machine.
Also could be a timing problem

Not sure. guess about 25 - 30 years

The needle plate is held on with two screws from the top. The feed dogs must fit in the slots and the writing faces up. Is that really your question?

A jammed machine is caused by thread being caught in thehook. Remove the upper thread and the bobbin case, turn the hand wheel towardsyou (counterclockwise) by hand and remove any thread in the bobbin case area. Alwaysturn the hand wheel towards you. Turning the hand wheel away from you(clockwise) can cause the machines timing to become unaligned and jam yourmachine. Also, always make sure the presser foot is in the down position beforeyou start sewing. Sewing with the presser foot in the up position will jam yourmachine in the bobbin case. If youhave an older model sewing machine with a shuttle hook, then you can alsofollow these: 1. Disconnect the sewing machine from any power source.Loosen the thumb screw on the left side of the sewing machine body and removethe cover to expose the needle bar. This is the shaft that extends down andthat you attach a needle to for sewing. Open the shuttle race and remove the bobbinand bobbin case. 2. Turn the hand wheel toward you until the needle hasreached the lowest point of the stroke. The hook should be at the top of itsstroke inside the shuttle race. Loosen the set screw for the needle bar on theupper part of the machine, this is located on the needle bar bushing (thecollar that the needle bar slides through when making a stitch). The needle barshould slide easily up and down. 3. Turning the wheel again, adjust the position of the tipof the needle so that the upper part of the needle eye is just below the bottomedge of the hook inside the shuttle race. Once in position, re-tighten the setscrew on the needle bar bushing. Do not allow the needle bar to slip whiledoing this. 4. Replace the bobbin and bobbin case and close the shuttlerace. Thread and plug in your machine. Using a sizable scrap of cloth, sew aseam to check to see if there are any skips in the stitching. If there arestill skips re-adjust the timing again until you can sew without any skipped stitches. 5. When proper timing has been achieved replaces the coveron the needle bar and tighten the thumb screw. Hope this will help you. Good Luck.

Make sure machine is set for regular zigzag stitch and not a fancy zigzag stitch, and rotate it by hand at least two full revolutions in the normal direction of rotation to make sure it is settled in to the regular zigzag stitch. Now set the stitch width to maximum width and slowly rotate it by hand, watching the needle. Does the needle strike the top of the foot at the extreme left or right? (and this is the slotted zigzag foot, right?) If not, you are good to go. If the needle does hit the top of the foot squarely, do make sure that the foot is mounted correctly and change the needle, making sure it is the correct size and that it is inserted all the way and facing the right direction. It is somewhat unlikely that the left to right position of the needle bar needs adjusting.

Looks like you will have to pay $10.00 for it...

I've had this happen a few times. It's usually because I need to loosen the needle clamp screw a little more to make sure I'm getting the needle PAST the screw and far enough up in the channel so that it can be caught by the screw. I hope this works. If it does, please let Fixya know by rating my solution!
Good luck and happy sewing.

I have one, I bought it for the cabinet for another machine. There is no manual but it does sew, I tested it. It looks like it has been very used. I could not test the fancy stitches without a manual.

Make sure you're using a polyester thread (I use maxilock serger thread) then a stretch needle, and hold the tails of your thread until you get started into the seam so the fabric cannot push down into the opening on the throat plate.

Also, a small zigzag stitch (about 1.8 - 2.0 wide) is good to use on lycra as that will allow the fabric to stretch after the garment is made.

This is stuff I've used with my 6500P and other previous Janome machines in making Ice Skating outfits.

Sorry, tried to find a free manual but could not.
