I am planning on going away next week in my Commer PB but the engine hasn't been running very well. I have fitted a new distributor because the old one had very worn bushes. I now need to tune the carb but my manual covers the Zenith carbs and my vehicle has it replaced by a Weber (as fitted to later PBs?). I am going to put on an almost new Weber from another PB because that way I can guarantee it has the correct jets. Can anyone please give basic instructions for tuning the Weber?
