Drilling jets

Since it seems a lot easier to drill a jet out than to pay $6.95 and wait for it to be shipped if you don't have a local store, I am posting this chart that relates bit sizes to jets for both the Dellorto and the Bing.

Here is a link to jet reamers made just for this.

Here is a link to jet gauges so you can tell what size you got.
