Lost spark?

Postby 71Nova » Mon Jan 26, 2004 5:28 pm

Was out plowin snow for about 3 hours and right as i was about to finish our driveway and the Cub just quit. I looked at the fuel supply and all is good. Checked for spark at the plug and there was none. Checked spark at coil none. Checked power to coil and there was power there. So i went and got a new coil and tried it and still no good. What could the problem be here?

No spark at the coil means the points are not making & breaking or they are bridged by a short. I'd check the points for glazing and check the wire from the coil to the points to see if maybe it is shorting out, The condensor could be shorted but that is a rare occurance. If you put an ohmmeter on the coil primary terminal that goes to the distirbutor and slowly hand crank the motor over, you should be able to see the points make and break the circuit to ground (ignition off - unless you have a magneto)

If you can't fix it with a hammer, you've got an electrical problem.

We filed the points and it fired right up. Problem solved thanks for the help.
