Yes their is. Your supposed to use the special skew tape to set it but setting it with a written tape probably will get it close enough. Thanks. .015 difference probably isn't that significant. I'll try 1.83. How long does this last? I got 4 new switches so I'll try this for the other 4. I like saving money. I expected the vacuum noise when running. What I was referring to was more of a grinding/scraping noise when turned by hand. There are a lot of things I plan to do. Hopefully this weekend I will actually create a page for it. At minimum I will docuement what I repaired and how. This will be the most complex restoration I have had to do. I'll post when I have something up.
