Briggs 8hp flathead rebuild - small keeper appeared

Interesting- so if the throttle goes to the extreme end (rotating the plate on the back) - that clip on the throttle plate will ground out the spark if the magneto wire is attached to the clip. Is the extreme position intended to be the “wide open” throttle position ( so used to prevent over reving the engine?) or the “off throttle position” which is used to turn the motor off?

One end of the slide position is designed as the kill. The other end is normally the full throttle position which basically pulls the governor spring straight down. The top no load engine speed is controlled by tension on the governor spring which is adjusted by bending the arm that the governor spring attaches to on the throttle control plate. Then engine speed can be adjusted between full and idle by varying the throttle cable position within the slide.
