The car is a late 1968 model with a B20a 2 litre engine and a single Stromberg carb. It always starts cleanly from cold (less so from hot), and I never need to use the choke, which I'm told is an anomaly. Also, it drinks fuel at quite an alarming rate.

Recently I met some Volvo enthusiasts and they suggested that the needle and jets used on these LPG-equipped cars are different from regular cars, which might account for the fuel consumption, hot starting and chokeless cold start issues. They suggested I change the needle, the jets and set the carb up properly for petrol-only. Can anyone confirm this diagnosis, and if so, which needle and jets should I be looking into?

Many thanks,
Ric
