Stop in for a cup of coffee

Think I found my mowers problem. Or, at least one of them. Primary side of the Magneto appears to have an intermittent open. Started right up this morning. Ran it a few minutuses. Saw spark etc. Turn off. Come back and no start. Checked resistance of coil per service manual and Secondary was good, but open primary. Let it sit again. Come back and got a few K ohms on primary. Popped the wires back on quick and it fired right up. Guess I will be ordering that. Plug wires (part of it)look crappy too -cracks. So really needed replaced anyway
