I had a warm hard start on my gen1 on a hot rainy day about 2 years ago. I pulled in front of a hotel entrance to put on a rain suit. I got ready to go and had an embarrassing hard start. I let it sit for about 10 minutes and held it wide open and it cough a time or 2 and redlined. I took it home and cycled the key at least 10 times and it fired right up. I killed it and cycled it about 20 times and it farted a couple of times. Then fired up and ran perfect.
