I replaced the switch box and still have no spark at all. The stator and trigger appear fine. Any ideas? <br /> Confused

Appear fine? You need to get an ohm meter and check the stator for opens. Disconnect the kill switch at the pack and see if she fires. You will need a manual for the resistance check. Also see if she fires with the sparkplugs out.

Today we checked for spark with the plugs out but no spark. We then checked for current to coils and found none when pulling the rope. Now we will<br />check the stator and trigger since we have eliminated the switch box as the problem.

Ohm meter shows high reading on 1 wire from the stator to ground but no reading from the second wire to ground from the stator. I may replace the stator and trigger since I don't know how to check the trigger.

Ordered the stator today and I am looking for the trigger assy.

I replaced the stator today and she fired right up. No need to buy a trigger. This info may help someone.
