For the starting procedure, I have not experienced that symptom. I've only started mine approximately 50 times in 24 hours of engine run time. Each time I do start it warm or cold (down to 7* F) it fires so quickly that I can not discern the sound of the starter. It is usually about one second of cranking or about 4 revolutions. When the ambient air temp is below 30*F it will chug grey smoke for about four seconds. I suspect you may have a loose battery cable connection on either the batt or engine end.
My experience with the deck has been limited to only one removal, so I can't be much help on that one. However I suspect your mid rockshaft is out of adjustment. With the deck removed lay on you back under the machine and cycle the MMM lift arms up and down to see what does what.
