hi, I do this. I put again in their place the two screws I found when I opened the machine. the hole that you see in the picture was fitted by a screw that I put away for cleaning
another screw was in the horizontal shaft and another, longer, in one side of the crank
the horizontal shaft rotate even without any screw
if I put two screws in the gear around the vertical shaft, and othr two in the crank, the vertical shaft does not yet rotate
I thought this two
1 is it perhaps some hole for the screw point
in the vertical shaft and they/it is turned back in the inaccessible side of the arm?and how, why? if the screws were inside when the machine frozed with gum
2 the shaft is so glued to contrast the force of the screw, even well and too tightened.
in this last case the only would be disassemble all to clean the shaft, because I don't know if an entire year of paraffin drops would be sufficient to unblock it ciao
