how about a build list and a how to make this magneto speed rig many still out there just can,t afford the ew garmin but can still get use out of theirs
also that bolt looks dry as street pavement, and maybe dragging due to how dry it is soak the bolt in mobile 1 synthetic oil for a couple of weeks the oil will adhere to the metal i the bolt and remain slick but breaking in a new gun you want it dripping wet....
