Getting skipped stitches with my coverstitch

I recently treated myself to the Coverpro 1000cpx and have been learning how to use it, thanks in no small part to all the information here on this forum! I was hoping perhaps someone had an opinion on what I should try to fix my issue.

I made a couple little raglan tops for my boys from an interlock knit (probably cotton, but it was tough stuff to even pin through, so maybe that means there was lycra in it?). All went well until I used the coverstitch machine with the center guide foot to topstitch around the neck band after attaching it with the serger (using the left and right coverstitch needles, not the middle one). From the top it looked fine, but underneath I can see that in several places the looper didn't connect with the needle threads. It happened pretty consistently where I went over the seams but really, the seams were not bulky (they were flat-locked and pressed). It also happened between seams, so the seams weren't all to blame.

I didn't have any problem on the hem, even over the side seams, but I also didn't have the rudder on the center guide foot on then.

I suspect the rudder on the foot is a good part of the culprit, but I'm not sure how to go about fixing it. Increase or decrease the pressure on the foot? Can the rudder be adjusted a bit? I was surprised at how much pressure that rudder put on the fabric... I wasn't able to get a flat piece of fabric started with the rudder on, it just jammed up, but it would work in the round.

My needles are new, but perhaps I need heavier ones? I have both sizes. (But which number is the heavier one!?)

If you made it this far, thanks!!

Are you using ball point needles? that will make a difference on knits.

Yes, you can loosen the screw that holds the rudder in place.

Try decreasing it a little.

Are you using ELx705 needles? This is a must when using a coverstitch. If you don't use this type of needle you will end up with skipped stitches. Ask me how I know...

The wrong needle is the #1 problem associated with skipped stitches in coverstitching. I see it as the solution on the PR boards and the Yahoo Coverstitch group I belong to all the time.

Yep, am definitely using the ELx705 needles.

I got cozy with my seam ripper last night and am hoping to try again tonight, with modifications to the pressure on the foot.

Thanks so much for your responses... I really all appreciate feedback on this forum.

Not sure if you know (may be useful to someone else), but if you just remove the last stitches of the top threads (at the end, not the beginning) you can pull the looper thread and it will undo.

oh I did not know! Will try next time! Does it matter if you do or don't pull the needle threads down when you pull the fabric off?

*yawn* Its time to call it a night. I made some progress, but not enough to call it solved quite yet. :)

Going slow and using a hump jumper type of thing seems to be the key. I used all kinds of different pressures and tensions with varying degrees of success. I'd get one decent looking seam and then the next one with no changes would be terrible. I'll do more testing tomorrow night.

I did notice it did better when the bulkiest (serged) side was under the right needle, but again, I need to test that theory, too.

I have been told to always use the 90/14 needles for knit fabrics. And use good thread, even for your looper. I have tried using a co-ordinating colour in the looper, a birch or one of our stores in Australia cheap thread and my CP does not like it. If I put in a decent gutermann or a good overlocking thread, I have no problems.
Over thicker fabrics, especially seams, you need to increase the pressure, so turn the knob into the machine, so that the fabric grips better. And go slowly. There is no such thing as fast with a coverstitch.
