The Racing B. and B.
Last week we described the new design B. and B. carburetter for 1912, illustrating its special features on page 1037. Our description applies to the light-weight and heavyweight standard models, but the firm have a racing pattern for those who wish to obtain racing results. This carburetter is similar to the universal type, but has a straight through air opening with an extension pipe at the rear. To adjust this carburetter, the throttle and air orifices should be placed in the fully open position, the jet being set to suit. The makers say that this carburetter, which is put on the market to oblige their racing clients, is not so controllable nor as economical for ordinary touring purposes as the universal models with the adjustable primary and secondary air openings. The variable jet is standard on the racing model as well as the others already described.
Readers will be interested to know that the firm has lately moved into well equipped works at the address mentioned, where even part will be made on high class automatic machinery, thereby ensuring accuracy and perfection of workmanship. We made a short tour of the works in company with Mr. C. Brown and his right-hand man, Mr. Evans, and found the works fitted up in the latest style. We mention the above as an instance of thoroughness and to prove to our readers that Messrs. Brown and Barlow intend to spare no expense or trouble to maintain their already high position in the motor cycle industry. A 1912 model was fitted to one of our machines in a few moments, and as we returned to the office by road we could detect an improvement in the running of the machine — a 3½ h.p. and sidecar. It is an advantage with a low powered sidecar machine to be able to increase the petrol supply uphill.
