How accessible are your fuel lines with the body on? Mine are inaccessible. Also, when i kill my engine, it's usually because I'm working on something or i've had a problem (broken something) on the track. In those cases, I don't want to have to wait to take the body off (while on the track) or if i'm in the pits have to prime the fuel lines again to get it started. I've been plugging the exhaust for years now and have never had trouble starting or hydrolock. I can see the logic that would lead to these conclusions, but when the engine dies after less thatn .5 seconds, there's not a whole lot of fuel spitting into that piston chamber. This is one of those "to each his/her own" things.
