Funny enough - when I got home last evening "Eva" started on the 2nd try for me. I had to pump the pedal a little but she fired right up!
This morning when "Eva" was taken out of the stable she fired right up again and gave my lovely bride a trouble-free day!
Maybe it wa a fluke?
Come to think of it - this is not the first time this scenario has happened. Maybe the 300E doesn't like to be started for 20-30 seconds and shut down again?
