Also, turn the lights off if you can.
Gives the starter motor a bit more punch.

may also be fouled plugs, so may be worth whipping them out and giving them a clean and resetting the gaps

In that case get those plugs out and clean them up. They are more then likely soaked in fuel now, so a good clean and heating with a blow torch or the hob if you have a gas one.
