Here's the problem: At random times, the advancing mechanism will not successfully advance my bisquettes.
This only happens sometimes. It seems that the "push plate" (the piece that retracts, allows the bisquettes to drop, and then pushes the bisquettes forward) is not always pullling itself far enough away to allow the next bisquette to drop.
Here's a video of it failing, when I've taken the generator apart. By the way, I had manually advanced several bisquettes before this successfully. This one was failing over and over. Later, I put the _same_ bisquette in, and it worked fine.
This happens at random times, with random bisquettes. There is no rhyme or reason. I cannot seem to determine what can be done to make the push plate retract completely for proper operation. And again, this doesn't happen all the time, but happens at least one time per smoke.
Here's the video. As you can see, nothing is getting stuck mechanically. The motor is successfully turning without obstacle. Its just not retracting all the way. https://youtu.be/nrO3qdRPKhc
