Finally have My engine out to do the sub-frame (hopped one too many speed-bumps on moped monday I guess), so I took the opportunity to change the crank seal and take the degree wheel to it.
With my very molested intake patch and an unmolested mazzucchelli anticipato; I get the intake opening at 132° BTDC and closing at 57° ATDC, for a total of 189° duration.
Haven't popped the top to check the exhaust and transfers yet, but it seems I have a bit to go, at least on one side. I rigged up a degree wheel externally. I made a spacer to tighten it down out of some tubing, but I suppose the center drive boss from the variator and some washers would have worked just as well. (edited)
