If this is like the temp sensor on the aircooled ones, there are two ways
it can fail.

If it fails shorted, you'll have trouble starting the engine cold (it will
be too lean.)  I suspect that's not the case if the plugs are wet.

If it fails open, the engine will run very rich.  It'll start fine, but
will flood out and die once it gets warm.

A quick test on the aircooled motors, with a cold engine, was to
disconnect the connector and see if the engine would start.
