Well we got there. Just moved it one tooth and its good. I spoke with the original owner. He swears it was never removed. I could have gotten it close without jumping the tooth. Probably about half of what it was out. My guess is that at Mercury it was installed "close enough" and it ran for a long time like that. Thanks SB! I'll let you know how it runs tomorrow. The black flies were killing me tonight!

Don't think close enough is correct but that's just me
Can get it precise by building the gadget in the file starting on page 15

Apparently close enough was good enough to get it to run for many years. However, I'm not a good enough kind of guy. It is now spot on per the merc manual 31. I'll see how it goes. If it's not running right then I plan to follow that TSB and build the tool. Seems easy enough.
