What size drill bit do I need to calibrate my autolite 2100.
I'm pretty sure I need 2 different sizes, one for adjusting before pushing piston in and one after.

 

where can i apply vacuum to see how the choke reacts? which opening is it on a 2100?

 

you want to have it in such a way that when closed the choke plate is nearly closed and when warm fully open. and when accellerating cold the choke plate opens to allow more air in (this is done with the piston in the choke housing).
The shop manual has exact procedure and drillbit size. other than that you only need a bent paperclip. However I find the instructions quite unclear so I used those. after using them I understood what they were trying to say in the shop manual

I'll check in that shop manual later
