Hmm, yes that makes sense. I'm sure this things has been reassembled incorrectly hundreds of times. plus this boat has been neglected in Norway for 5 years before being picked up and converted into a research vessel... Bending the pins is probably what allowed them to fall out.
(it was like that when i got here, chief!)
I used DEVCON to reattach the pins, test- ran it for 24 hours, no vibration, seems to be working good. new distributor on order, though.
