Don't attempt it!! Get a friend or two to push you. If you're towed you will end up making impact with the car bumper due to your gearing being higher than the towing car, hence you will shoot forward. Seen it happen and it worked out expensive for both parties. You can buy/hire starter/booster packs for next to nought if look on the web, safer all round.
Turn the key to on, turn the start button to the start position, put it in first , start running along side it holding in the clutch in and when you've reach max speed, jump on and let out clutch. If that doesn't work, tow it about 10 mph and do the same. Should fire up.
