I considered it, but part of the hand drawn diagram is missing where the paper was torn off. Since I don't know what that is, I decided not to try to recreate it. However, since you brought it up, my interest has peaked, so I am thinking I might actually try to find that sketch.
It's interesting now that I go back and read the document. I should have paid more attention!! There is a line in the instructions that in bold letters tell you to BE CAREFUL turning the brass nut on the starting switch. THIS IS VERY EASY TO STRIP. I found out the hard way. I had to replace the coin mech activator linkage that is screwed onto the starter switch. There is supposed to be a square piece on top of it that was broken off, see pic below (You can actually buy this piece,other pic below, from Funtronics, which amazed me, BIG THANKS to FUNTRONICS). To replace the linkage you have to remove the brass nut that attaches it to the starting switch. Mine had "fused" to the threaded shaft that comes from the starter switch. I turned the brass nut and it seemed to unscrew easily and I did not realized it but I twisted the shaft off. Now it was too short to put the linkage and the nut back on.
The name of the company that made the switch was stamped into the switch housing and amazingly enough they are still in business. I called them and sent them a pic. They were very nice and actually talked with some of their long term employees, but the part was not available and had not been for decades. I got lucky and was able to replace the shaft with a long screw. Had to drill out the old shaft and was nervous I would crack the ceramic housing the shaft ran through. fortunately it didn't crack and the replacement worked. See last pic below with new threaded shaft and Funtronics replacement linkage
