32mm or 40mm Jet Needle

You may find yourself in this position - I did.   I'm rebuilding my 32mm bing carbs and having ordered a new set of jet needles I noticed that they were a little bit shorter than what was installed.

It turns out there was a simple shipping error from a very reputable and super company who I called and immediately set about to get me fixed.

In the process of researching however, I noted a lack of simple information about these needles.

Length of Main Jet Needle

Pre 05/1983 Bing 32mm is 61mm long

40mm is 55mm long

For what it's worth.
