Welcome to JUST ANSWER small engines, let me try to help you !! Explain problem. Is the engine cranking over, just not starting. This is not vapor lock! If engine is cranking over, can you remove the spark plug, and with it grounded to the metal of the engine. see if you have spark at the plug tip.

With spark plug removed, the fluid will come out when starter spins engine.

Don't c a spark when I try to turn over
Expert:  Curtis B. replied 1 year ago.
This is with spark plug grounded to the engine? Did you try a new spark plug?
Customer: replied 1 year ago.
No its just not cranking battery maybe low by now. Can I just touch 0lug to engine to c spark.
Expert:  Curtis B. replied 1 year ago.
The magnet in the flywheel and the coil make the spark. The engine has to be cranking before you get any spark, and engine has to be turning at good rate! Charge your battery and then try it!
