Old start not cold start

Hi List,

My original post was why Spridgets didn't start after standing for a few 
weeks in the winter  (my only theory is that the plug ends get rusty and the 
spark is poor).

I already know why they are hard  to start when it is just cold - the petrol 
does not vapourise effectively so the mixture is too lean to burn - hence a 
richer mixture.
