Mine was the same way, until I adjusted my valves. It's still hard to start sometimes but the full throttle, hold decompression lever and 10 kick method also helps a lot. If I'm at home and it's cold outside, below 45F, the only way I can get it started is by worming it up first with a heater. I take my Reddyheater, and aim it at the jug for about 5 minutes. Once the engine is warmed up it will start on the first kick every time. But that doesn't help much when you're on the trail.
