Cosgig- “lock up at full throttle”
Am I understanding that if you hammer it hard it will do what I call “over camming” and hold the throttle open? Is this what you are referring too? And Thank you for your comment. And “Yes” I have the complete set up for the behind the head mount set up as described for 66’ formula S.
I read somewhere that the production throttle linkage was changed to the "slider" type mid-year 1966 because of the potential safety issue.
