Timing w/o handcrank

[COOTER]

Car was running just fine but suddenly died while driving. After a little troubleshooting, I found that the screw that holds the points to the upper plate came out and was floating around in the distributor body....so I had to pull the upper plate to get to it.
I'm assuming at this point the timing needs to be reset? I do not have a crank to spin the motor. Is there another way to do it by hand?
