Lately, sometimes it starts right up, but about half the time I find myself giving the gas pedal a couple pumps to make the engine turn over. those times, even though i haven't done anything different, the engine won't start unless i feed it some additional gas by pumping the gas pedal about twice.
it's odd to me in that rather than starting becoming hard all the time or just impossible, it's unpredictable.
does it sound like starter problem? something else? thks in advance
