With an accurate and repeatable way of determining crank angle, cam timing becomes quite straight forward. A dial gauge on cylinder #1 inlet valve showed maximum lift at 117 degrees ATDC, a rather large 7 degrees behind the reccommended setting of 110 degrees ATDC. On a crossflow, the cam timing cam be adjusted using offset dowels to positively locate the sprocket on the cam. The dowel can go in either way, to advance or retard the cam, but the head scratching paid off and I got it fitted the correct way first time.

With the camshaft timing done, the sump can go back on.
