Biohazard
Since I was having such a hard time getting her to start on her own, I thought filling the tank with fresh petrol wouldn't hurt. By doing this, I discovered how rotted-out my filler neck grommet was when I created a lovely cascade of gasoline pouring out from under the back of the car onto the garage floor. Of course, I had to kick the ol' girl out of the house, into the driveway again.
-Got a new grommet coming and it looks like someone already drilled out the tamper screws for the flip-cap and put phillips heads in there. Finally! A break!
