11633 has been out when rain started a couple of times. Both times (including about 15 minutes ago) it is incredibly difficult to get it started. This time I actually ran out of juice from cranking and had to boost it. When it did start, it revved up so high I had to shut it down almost immediately. Something (I believe belts slipping) made one hell of a noise, and there was a burning smell.

Are there any common culprits I should look for in wet weather which might cause this?
