Im in the process of a complete restoration of a 109 1963 11a petrol. I tried to start the engine after a full rebuild and ive got some carby problems. In the process of rebuilding the carby i replaced all the jets. I could not read the numbers on the old jets and tried to match the sizes as close as possible. The kit had more jets than were needed. Does anyone know where i can find information on what size jet should be where?
