I'm trying to help my daughter with her lawn mower (Sears, Craftsman). In
the past I've always been able to start them by spraying gas onto the air
filter. This time no luck. I have spark. The ignition is electronic. The
manual says that one of the possibilities is a loose blade. I have the
blade off the machine.
How would the engine know, or care, that the blade is loose or off?
Any ideas?
Thanks, Ivan Vegvary

It acts as a flywheel.

Richard (and your manual) are correct. The crankshaft will not have enough
momentum to get through the cycles and actually start running without the
blade firmly attached. And you'll feel the difference when you 'pull it
through'.
The other problem is you "spraying gas onto the air filter". Not only is
this a fire hazard, but it will also score the cylinder wall (sooner or
later). Definitely not good for your equipment.

Why is fuel vapor from the filter any different than from the normal
carbueration?

Actually, it's flushing the grit through the filter into the air
intake where it gets eaten by the engine...and fuel isn't
vaporized in those little carbs very well, but if you have an air
filter full of vapor and saturated with fuel, one little backfire and
the excitement begins....
