I am trying to set the timing and new points gap on an 08 concrete saw. I have marked TDC with a dial indicator and marked 0.08 inches BTDC (as per a downloaded service manual). Same manual specifies points gap should be 0.016". I have a buzz box connected to the kill switch wire to precisely locate the moment the points open. The manual also specifies that the edge gap should be 0.24 to 0.35" at that moment.
There seems no way to hit those specs. With the points set to 0.016", and the edge gap set to 1/4", the timing is way advanced. At the limit of adjustment, the edge gap is only about 3/16". To sufficiently retard the timing, the points gap has to be closed down to almost nothing.
At the moment, I've compromised by setting the points gap to 0.012" and leaving the timing somewhat advanced with the edge gap at 3/16". The saw runs, although I don't have any concrete to cut right now.
Any idea what I'm missing here?
