Ok, the manual states to set the mark on the drive washer with the mark on the engine case. I did notice that at this point the piston is not quite at TDC. I guess this is what tande alluded to. Then check the dot on the camshaft. As Four Stroke mentioned, the difference between true TDC and the marks aligned
does not amount to a whole tooth off on the camshaft. At this point, I'd stick with the manual. I will set the valve clearance so that the intake is at the low end of the recommended range (~0.002'') and the exhaust at the high end (~0.004''), to account for the higher temperature the exhaust
valve is subject to, unless your experience suggests otherwise.

With any luck, I should have the valve cover here by Saturday...
