I had my carbs tuned today by the genius who is Bob. He also teaches at Type 2 Detectives. My bus is now running so much better! He also fitted a fuel regulator and a Bosch dizzy with vacuum, replacing my electronic 009 (for sale if anyone wants it). The problem I have is that once the engine is switched off, I sometimes get a little fuel leak around the back of the carbs. It is not nearly as bad as before the fuel regulator was fitted. Is my next step replacing carb gaskets? Can I fit them without undoing all Bob's good work? Thanks
