Yes, I know it isn't a car, but bear with me....
My 16 year old son has a 55 plate Peugeot Speedfight 2. It did run fine until around November, when he started having trouble with poor starting, lumpy running and intermittent loss of power, to the extent that he is now unwilling to go out on it in case he can't get back.
When it does run, it runs fine, so I presume it is something external to the engine, rather than internal. Last week it had stopped running, so I checked for a spark, and checked that I could petrol through to the carburettor (by sucking on the vacuum pipe) and since then it has been fine. However, I presume whatever the fault is is still there, and am just waiting for it to happen again.
Is there a good resource somewhere of things to check in sequence (or to try replacing) to see if we can eliminate the problem ?
