Do you remember the Mercury "Leaf Spring" Clutch?

Since my return to karting, I have not heard this particular clutch mentioned. I don't remember the particulars when Mr. Vail (Crescent Raceway) suggested to me to try out and evaluate this clutch in 1964--a new item the shop started carrying. Mr. Vail told me what to expect, and what changes (gearing) may be needed with this high rpm release clutch. Once dialed in (gear ratio) a consistent .3 of a second improvement over my best time.

I love these old ads.  The photos are reminiscent of the FBI's "Most Wanted" posters you'd see in the Post Office.

Mercury was here in Canton, Ohio. I went down to the address a year ago and the brick building is still there. It has been revitalized and now houses several other companies inside.
