Hi there,
This is my first post so go easy please!
I'm restoring a 1974 series 3.
I have some questions about the carburettor:
1. In the first photo, is my holding the end of the "smith and sons" vacuum thing. What is it and what does it connect to?? I've started and run the engine, and if I don't put my finger over the hole which is sucking in air then it judders. As soon as I put my finger over the hole it's fine..
2. In the second photo it shows where the pipe in the right of the first photo connects to the oil filler pipe.. Could someone tell me what that connects to as it doesn't seem to fit in the "vacuum" thing in the first photo...
Thanks for any help in advance!
Tom
