I have been on Burlens site and they list the carbs through the years used and spares. What would be the difference between 73 to 76 B1DJ, 74 to 75 onwards B1DV, 77 to 79 B1EU, 78 to 79 B1FB metering needles. They all use the same jet.
I contacted Burlen but all they could say was they have different profiles and give different driving characteristics.
I think these were UK vehicles. Just confuses me especially when they use 2 types per year set.
Any help would be appreciated.
