purchased a new strikemaster, took it home added new gas and have had no luck starting it. it is the solo 2 hp. Followed their starting instructions to the letter with no luck. Checked plug for flooding and it is ok. Checked for spark and that's ok. I can get it to fire for a second or two with the choke on and pushed to full throttle. Strikemaster is out until after the first of the year. Is this a common problem or is it my bad luck. Any thoughts or suggestions would be appreciated
