Marty,
I observed that, after shutting down, the temp
in the engine compartment was so hot, the gas
left in the bowl boiled out. You can listen to
it perking. This fuel ends up in the intake
manifold creating a flooded condition.
By locking opening the throttle after shutdown,
sure,you squirt a shot of the fuel in the bowl
down the throat (it's going to boil off and end
up down there anyway). If you lock the throttle
open, it allows the stuff an escape to reverse
the flooding.
Hope this helps from Wayne in Northern Michigan.
