I can claim no extensive knowledge of the infernal combustion engine, however, being also stuck in Michigan, the winter is a good time to read. The only book I have which deals with 2 cycles extensively is "Tuning Your Two Stroke Engine" by K.G.Draper A.M.I.M.I. and published by Coles in Canada, c1977. I picked this up in a used book store, an excellent source for interesting motohead books. I would guess that you may have some success at your local library.
On the subject of firing while the inlet port is open, I am helping one of my neighbors to re-build a small 2 cyl outboard and I am fairly sure that he had this problem. However, I think it was caused by oil on the points from a leaky top seal causing it to fire at odd times. When we ran it in a tub in the driveway, it coughed and sputtered and banged and actually blew oily bubbles out of the crancase halves joint.
I think this is avoided in the average two cycle because the mixture is being blown in under some pressure and the inlet port closed fairly early in the cycle. This said, I have experiences an occasional "pop" from the carb.
