[Healeys] carb lifting pin

[Bob Spidell]

There's an inexpensive SU tuning kit that is little more than a couple plastic tubes you stick in the inner part of the vacuum piston, and a couple of bent wires you stick in the tubes (there's also a handy jet-centering 'tool;' it's almost worth buying the kit just for that). 

Anyway, you put the tubes in the vacuum pistons then set the wires in so they point exactly to each other. Then, when you lift the pin you can see the wire rise; the wire is about 1/32" thick so when it rises one of its widths you're close. 

Yes, the pin goes up a ways before it contacts the base of the vacuum piston.

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,
