20T rough start and burning fuel smell..

[jondsg]

hi guys
Noticed this week that when I'm starting the car of a morning its. Taking longer than normal, and sounds rough for. Few seconds.
Iv also noticed a burning fuel smell, if I'm out the car when first starting?
Any common issues like this? Or any ideas?

Thanks

Expensive fix?
