Easy bigger advance limiter bushing for MSD distributor
I wasn't able to get the ignition curve that I wanted with the bushings and springs supplied by MSD on my 8534 Pro Billet Distributor. I needed to get 25º initial timing, so the advance had to be limited to around 10º, and the biggest MSD bushing limits it to 18º.
I found a bigger bushing on ebay, but I didn't want to pay U$35 plus shipping and taxes since I live in Brazil.
So I just got a couple hex nuts with the same internal size of the bushings, so they would fit the pin that holds the bushing, and used a file to round the corners and shape them to the size I needed. You just need to round the corners a little so the nut can move free inside the slot.
Hope this can help someone.
