Do you mean spray the starter spray in the spark plug hole?? Or take the carry cap off and spray in there?
Also, an air leak. Like the carry body has a fracture? Or the on the spigot that is screwed to the engine is worn?
And what is the air leak doing? Causing the engine to flood?
For me I not only want to fix the problem I'd like to understand what the root cause is as well so any more detailed advice would be great help.
