This is crazy! I've owned a stihl kombi tool for years, and it starts on the first or second pull (always). So, I upgrade to a HT100 (exact same starting instructions) and I haven't got it to hit a lick, and I've been trying for over a week. So, I take it back to the dealer and his tech starts it on 2 pulls without priming or choking it. So, back to the house, no priming, no choke, and no start. So, back to the starting instructions again and still won't start. What's going on?
