Well... I took out the filter (let it dry overnight), checked the spark plug, kept it on a battery charger overnight. Today... I put it back together and... It WORKS!!!
My Blur is running! I could swear I heard it cough out the word "IDIOT" as it turned over.
I stopped at the same viaduct to look where I had fallen. Yep. open manhole. It was about 18-24" deep, plus the above sea level water. I fell in about 36" of water. YUCK.
Fortunately I didn't injure myself.
I'll post the video from my helmet cam later today.
