I ground off the pins.
Then I had to use lots of contact cleaner to wash out all the aluminum from the switchgear.
Then I mounted the pods and found they were loose.
I was not happy and was feeling quite dorkish, thank goodness my old friend Dave lives so far away, he would have died laughing at me.
Anyway, some skillful application of tape on the bars took up the gap, and all is well. I also found that too much tape, or tape in the wrong place, was bad news - as in pods that would not close down and throttle dragging.
Ahh, but what would I do next time ?
Grind off the pins, clean out the grindings, and carefully tape the bars.
Over the years I have found that when I change bars, by the time I align everything the way I want, the factory location in terms of rotational position on the bar, is not precisely where I want it.
