New Carburettor

This carb made the engine run a bit rich initially, due to the original mechanical fuel pump being replaced with an electric one. The original pump sat right in the space required by the new Weber. I have now arranged a return fuel pipe taking any excess fuel back to the tank. This has now reduced the fuel pressure, and allows the engine to run very cleanly. Starting is now first time every time, and tickover is like clockwork. Just how it should be!
