Hi all,
        Time for lesson no. 17 on the operation of a carb...
Where does the lift for the piston originate from?

The running saga goes like this: I did the Twist detox on a '76 and for some
reason, after all was said and done, each time I tried ignition, the car
chugged and never caught. Inspection showed that I immediately flooded it.
(Well, 2 weekends worth of inspection.)  Took the clean end of my trusting
cleaning toothbrush and jammed it under the piston and it started right up. 
I should add that the end of the toothbrush also opened the throttle disk so
maybe that is the element that allowed the start.

In any case, I still want to know what provides the lift on the piston.
Anyone know of a particularly good reading source on how these beasts work?

Thanks,
Bill
