Ok - so I'm trying to understand the relationship between piston travel and point function to properly set the timing on my 35 hp Chrysler with magneto ignition. I've found the thread about using the flywheel teeth to measure crankshaft rotation. The picture above shows the timing plate with the #1 piston at TDC and the points totally closed. I'm hoping a Chrysler guru can help me out with the following:
* Points should be gapped at .02" and timing at idle should be set at BTDC 32 degrees?
* When does the spark plug fire, when the points just begin to open?
* If the spark is supposed to occur before TDC why haven't the points already opened with the piston at TDC?
* Where should the point follower approximately be in this picture if the timing is set properly?
Thanks!
