I have sometimes, and sometimes not. It is easer to remove it, so that is how I will do it next time. I have no Twink now, but it is the same deal with my Cortina with side drafts.
I take off the distributor cap, and mark the shaft with a felt pen, and the alignment of the rotor. Then watch how much the rotor moves when you pull the distributor.
It is real simple to get it back in in the same orientation.
