Also I’d recommend only buying carb parts from Burlen in the U.K., especially the diaphragm. I’ve bought aftermarket ones and they’re not good. I personally replace the diaphragm annually and keep a spare in the car. If the car is new to you it’s a good idea to replace it. Make sure when you screw the carb top back on after replacing the diaphragm that the alignment line on the carb top matches with the line on the carb body. See attached photo. It’s a 5 minute job. Change diaphragm and set the fuel mixture at idle and see how she runs then.
