I have SM Laz Mag too... HOWEVER Mine is 24 years old and runs like it was new. I will tell you how I start mine.
1. Loosen Gas Cap Vent
2. Turn the cut-of switch to ON postion
3. Full CHOKE
4. Pull 1 to 3 times until it starts, now the trick!!!!!! Take off the Full CHOKE and Half CHOKE, warm up 30 seconds and a few Revs, then OFF CHOKE.
I would WAIT for another SM Laz Mag (more recent) to chime in here since mine is 24 years old. Also give ALL DETAILS (2-stroke? 4 stroke? Honda? Ect...).
Lastly the Owners Manual at
www.strikemaster.com or Tech Support Phone number
Good Luck and I am 99.9% you done no damage to it.
God Bless
