Domingo,

I didn't see anyone else answer your questions, so I'll take a shot.

1.  The gear on the distributor shaft drives the tachometer.
2.  When you spin the oil pump, you are turning just the pump.  You couldn't 
turn the engine via the oil pump drive -- gear ratios are all against you. 
It's why you must remove the intermediate shaft, which has the gear which 
engages the camhaft in the 1600, jackshaft in the 2000.  The discussions on 
this subject recently noted the difficulty one can have realigning the 
intermediate shaft with the oil pump once you're done priming the engine.
