ok
Technician: Curtis B., Technician replied 8 months ago

Can you remove the kill wires from the two coils and see if you have good solid spark? If you do, you have an oil pressure switch killing the spark.

remove the sparkplugs and the unplug the coils and see if I have good spark? I guess I don't know which ones are kill wires
Technician: Curtis B., Technician replied 8 months ago

The coils are mounted next to the flywheel, Each coil has a single small wire, that is the kill wire. You just need to see the spark at the plug or plug wire with kill wires removed.

Ask Your Own Small Engine Question
Customer reply replied 8 months ago
No spark
Technician: Curtis B., Technician replied 8 months ago

No spark on either plug? Did you try it with the kill wires removed from each coil?

Ask Your Own Small Engine Question
Customer reply replied 8 months ago
No spark on either plug. Which is the kill wire there is a black and yellow wire that plugs into each coil
Customer reply replied 8 months ago
One coil has yellow and black the other has blue yellow and black in the plug
Technician: Curtis B., Technician replied 8 months ago

Unplug all the small wires and see if you have spark.

Ask Your Own Small Engine Question
Customer reply replied 8 months ago
Both coils unplugged no spark
Technician: Curtis B., Technician replied 8 months ago

Could coils be damaged by having voltage ran to them? Seems that coils are bad, but why would both coils be bad at once? How did problem begin?

Ask Your Own Small Engine Question
Customer reply replied 8 months ago
Sat for 6-8 months got it to fire but ran rough so took carb off rebuilt it put it back on and no spark once in a great while it would spark and even got it running last week but now nothing again
Technician: Curtis B., Technician replied 8 months ago

Everything points to two bad coils. The coils and the magnet in the flywheel are all that makes the spark.

Ask Your Own Small Engine Question
Customer reply replied 8 months ago
Ok
Technician: Curtis B., Technician replied 8 months ago

OK> get two new coils and try it.

Ask Your Own Small Engine Question
Customer reply replied 8 months ago
Ok that might take a little bit
Technician: Curtis B., Technician replied 8 months ago

Yes, have to be ordered.
