I saved the timing manual to my computer.
Thanks!

When I run the 99 without thread, it runs like a champ 100% of the time. When I sew, 95% if the time I have no issue. The other 5%, it gets "stuck", or the feed dogs seem to stop advancing the fabric. I stop, remove thread from needle and give it a go that way...and there's nothing that appears wrong! I'm starting to think that either this machine doesn't like me, or that it's possessed. I guess that just gives me a reason to look for another, LOL.

Yes. Look for another. One more reason to tell your DH that you need another 99k :)

are the "tails" from the threads getting stuck. Trim off the old ones and hold out the new ones when you staet and see what happens then, don't "pull" them. Does your needle plate have burrs either top or bottom.just my 2¢

Hmmmm,

A few ideas:

Is the top tension tight enough to stop machine?
See if you can find exactly where the thread is binding.
Check out figure 3, is binding occuring due to lack of thread clearance and/ or did you remove that screw in photo.

Very puzzling,
Jon

Jim...the tails aren't getting stuck. I have been gently holding them out of the way until I'm sure there's no way possible of "stuckage", unless I'm doing something wrong, which we all know is possible. Checked for burs, nothing there either.

Jon... I sigh, lower my head, feel my cheeks turning red, turn my head in embarrassment, and sadly admit I removed the screw. After I did it, I saw in another manual that is says to NEVER remove the screw....but I did. Arrrg!

When I first got the timing fixed, I noticed that the thread was really hard to pull through and up, and figured it may be due to the thread clearance. What I did was loosen the screw, just a trifle, and it seemed to do the trick...but with my luck, I probably wrecked something else. Oy! :mad:

I guess the thread getting stuck in and around the bobbin due to the thread clearance could cause some binding, thus making it seem like the needle doesn't want to move, right? It would explain why when I pull out the thread and run the machine by itself all is well. However, it still runs fine most of the time. I wonder why it's only happening intermittently?

What size needle are you using? What size thread?

Tension discs are clean ?

*sigh* there are several blog posts I would point you to, but I keep getting my hand smacked for pointing people to uh,.. a site that may or may not belong to me. I could have shown you timing things, tension things, 99 bobbin area things. :(

This will help some though: http://www.quiltingboard.com/vintage...g-t195869.html

As will this:

First, the stuckages could have to do with an intermittent catching of the top thread. When it happens, gently pull on the thread to the left of the tension disks, does it move relatively freely? (it will have some tension on it, but shouldn't be "Stuck". ) If it doesn't, pull on the thread on the right side of the tensioner, is it free? If it's free on the right and not the left, the problem is either the tensioner or something (duh!) to the left of it. ;) If it's not, I would first check the spool to make sure you're not catching on the little "slit" on the spool.

If it's on the left: check the needle plate, the entire thread path for burrs. Can you post a photo of the stitches, preferably with a different color in top and bottom? (If you take the throat plate off and watch the stitch being formed, it's also very enlightening... that top thread does a lot more than the average sewist thinks it does. ;)

Screw "EE" being loosened and things being adjusted are not the end of the world.

Tammi,

I'm curious as to the trouble with pointing people to a site that may or may not belong to you. Is this a no no?
