Can someone with a 1979 ESM book look up under the heading 'Specifications' 'Electronic Lean Burn System' and tell me if it lists Spark control computer number 04106086? It will be about page 220.

Hi 1978NYB The electrical manual I have 1978 has nearly all that I need but frustratingly does not list my particular Spark control module which is a 04106086.Is this in the 77 or 79 edition? Can you help looking the timing data up in one of these?

Hi Spent the day getting to know the carb and electrics for the engine. I'm liking the Electrical service manual but it does not list my SCC 04106086 so I do not have the throttle/vacuum advance figures. Can someone take a shot of their manual and send it please?

The distributor is the single pick-up type so I guess I will also go back and check all leads for resistance. I am thinking also to check compression and give the carb a run through as a starting point.

Thanks for the feedback. I await the manuals. In the meanwhile the leaner than lean burn is interesting so I will check again for leaks. Could a temperature sensor failure cause this? Appreciate your responses. Bill

Hi The Bristol ( Fitted with 360a 1978 lean burn) is having its problems at the moment. Whilst on holiday in Normandy the petrol pump split a diaphragm, and the car later decided to shed an exhaust entering a Chateau.... But the main bug is that -when hot - the engine restarts but dies as soon...

Hi Jack I too would like to keep my lean burn going. Would like to have one of these boxes as well, but they seem to be rare. Would you be able to help with an issue I have on hot starting?

The Bristol 412 was built with a 360A in 1978. This is a fun car but the lean burn will not run from a hot start unless left for a minute. Location: Kingston upon Thames UK
