This carby was a good income stream for the carby rebuilder because these carbs proved to be a poor performer as far as service life between rebuilds go. Several rebuilds during their life would be required to keep them operating satisfactorily. The four long cover screws around the air horn were the biggest design fault causing the top and main body to warp substantially. These carbs can be straightened if done very carefully with a little heat applied. Most of the time it was more practical to fit a Holley 320 or 350 Holley. This schematic is for a flat stem pump plunger which needs the Fuelmiser kit CA-157. I have modified the schematic to suit Aussie model.

The service manual link covers at least 3 different models of the BBD, mainly USA but most adjustments apply to the Australian versions also. Take caution when applying adjustments from the manual that it is for your model. BBD Service Manual
