[Healeys] carb lifting pin

[Bob Johnson]

The fuel mixture thread talked about the lifting pin. Does anyone have
a good way to tell when you have raised the pin 1/32"? On my car it
seems as though the pin raises maybe 1/16" before it feels as though
it is contacting anything and then I start to raise the needle. Is
this right? How can I tell if I'm actually raising anything and when
have I raised the pin 1/32" when I can't see anything?

Thanks,
