I have a 1970 6 hp seahorse, the throttle handle spins freely and the long linkage comming from the handle spins, but where the linkage goes up, theres no mechanical movement at all. shouldnt i see some movement when i turn the handle under the cover also? i just recently got the motor from a buddy. there was a short pin, along with a bobby pin looking pin taped to the handle. i cant seem to find where it goes, maybe thats the reason the handle freespins? any advice would be greatly apprectiated. thanks
