Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, and thank you for choosing Just Answer. My name is***** will be happy to assist. Have you checked to see if you are getting spark to the spark plug on the faulty cylinder, immediately after it fails?
You and I need to determine if our problem is ignition related, or if our problem is compression related.
Is your engine a Briggs & Stratton brand?
Disconnect the small black kill wire from the ignition coil on the faulty side. Let's see if this your ignition coil will resume firing, after you remove your kill wire.
If so, then you may have a faulty diode in your wiring connector. If not, then your ignition coil could be at fault, although it has been replaced.
You and I can continue from here. Thanks!
Thanks for your reply. Yes, the small black wire, is your kill wire. Have disconnected it yet, to see if your faulty cylinder will perform satisfactorily?
