I have never had any starting issues, although occasionally the initial idling is a bit odd, uneven if you will, but a quick bit of throttle sorts it.
I start it as the manual says to start it! Shockingly enough!
I put the clutch in, turn the key to MAR or whatever, the first point where you can hear the fuel being pumped down the fuel line, (try with the door open, you will hear it), then once all the lights have gone out, turn the key to the end and it tends to start very quickly.
As someone mentioned, putting your seatbelt on between half turn and starting is a good habit, as the timing is perfect. And you avoid the screeching beep of the 500's anger at you for not wearing a seatbelt.
No problems!
