273 won't start regularly
Busy morning. Got new spark plugs, ohmmeter, and timing light.
Resistance across coil was 1.9 ohms across coils (higher than 0.75-0.81 recommended) and 9500 from center to side (slightly lower than recommended)
Also checked for play in the rotor, photo is attached. I superimposed lines showing about 15 degrees of angular play.
Timing photo is below that one. I put some chalk on the wheel around the mark, so that is why it is white. Sorry I couldn't get a better focus on the camera.
Ironically, before doing anything at all, my wife started it 3 times in a row. I think I'll switch out the coil anyways, so I'll see if that makes it start more reliably.
I think the spark looked a bit weak, but I'm not sure exactly how strong a normal one should look.
I'll let you know when I change the coil and plugs if the spark is better.
