most definately the most common thing for a 2 stroke engine non starting is a fouled spark plug a new one is £3-£3.50 to buy

spark plugs can work well in open air but under compression fail.if it is bad then a new 1 is needed even if this is not why it wont start at this moment in time

I can answer this question...
will a bad condition spark plug with a spark stop my bike from starting?
