Long story short, standard eng. shut-down, main fuel pump switch
to OFF, half second or less, eng. quits rather
quickly. """UNLESS""" you are low on fuel,,, &
picked up some air in the lines,,, eng. remained running,,, after
shaking the thoughts of gremlins out of my head, possible as long as 20-30
seconds & quick look at fuel gauge for tank I was on the thought came to me
that I picked up air from empty tank & pressurized it with fuel pump, I now
have an air pressure-fuel pump backup sys. so eng. will remain running, had to
shut down elect. to stop eng. How about that one to start the
year. David R. Cook RV6A
