Since I haven't gotten that one going I'm using the #128 but the 99K sounds soooo quiet! The 128 sounds quiet too but not as quiet as the 99K. :)
The needle could be dull, bent, the wrong kind or not installed correctly. The flat side of the needle faces right, and the needle is threaded from left to right. It also says to be sure the needle is pushed all the way up into the clamp, and mentions that if the thread is too thick for the needle that also can cause skipped stitches.
I have an older 99 from 1934, but the manual I have is for a 1957 model 99. It does not mention "K", so I don't know what all might be different. Just hope this helps.
