Engine had been running at idle for maybe 5 or 10 min when I took the readings, but given the balmy Canadian climate (sub freezing at time of test), it's possible it hadn't reached full operating temperature. Will re-run after a serious warm up and see if the deviations drop.
For future reference, anyone have any sense for how much adjustment CAN be done via fine tuning (i.e. via the camshaft sprocket)? Are we talking a degree or two only or several degrees?
