Austin Big Seven starting problem

[Nick Salmon]

Interesting range of experiences concerning fuel. I am quite prepared to believe that other factors may affect the ignition of the petrol/air mixture. However I believe that if a component in the process is less than correctly adjusted or not quite in proper working order the older petrol will be less forgiving than fresh. 

Have a read of what BP were saying a few years back:
