Peugeot Jet Force 50 - Advice Please

My son's been given a 2004 Jet Force 50 in readiness for him turning 16. It's in generally okay condition, low mileage but is a non-runner.

It's got a healthy spark, clean fuel, good battery. It seems to be over-fuelling massively through the direct injection unit in the head (seems very overly-complicated for such a weedy engine) and soaks the plug before it has a chance to fire.

Any pointers much appreciated. TIA

 

My advise would be to get rid of it, you'll be spending on it all the time, spares are not easy to find, it's old .
