OK, I found one by searching Gogle. They show a V765-01 and a V765-03. The -01 is $192. Is that the one I want?

Yes, the -01.

with ferret adapter timing is set at 2000 rpm, you must use a standard timeing light that has tach built in and a **** to adjust the advance of the light to line up the timing marks, then look at the number on the advance **** to see your current engine timing. at idle my engine is at 12.5btdc and when reved to 2000 it moves to 6.5 btdc this timing change is normal.
