The engine runs fine at idol and then the revs start to go up and down quickly once you give it some revs...
I have posted a video on youtube - link

Check to see if that pink wire is grounding out to send CDI into rpm reduction, I have no idea whether your advancing full throttle (which shouldn't on flushette). Might have a shift switch to prevent in neutral reving. I dont know what your model number is?
