Why does my zero turn keep backfiring?
A spark plug that is damaged, worn, or has an improperly set gap between its electrodes creates a weak spark. As a result, the fuel may not ignite in the cylinder, but it might ignite when it reaches the hot exhaust muffler. The result is a loud backfire. Poor spark also results in a mower that runs unreliably.
Can a worn out timing belt cause a backfire?
A worn out timing belt can upset the combustion process and lead to backfires. Gasoline engines need to fire spark plugs on time to properly ignite the air-fuel mixture inside a cylinder. On time means that sometimes the spark needs to be fired ahead in advance or retarded depending on engine speed and load conditions.
What causes an engine to backfire after months of use?
For example, a spark plug gap may widen after the plug has been in operation for months and make it difficult for the spark to jump. Also, carbon buildup may isolate the electrodes, preventing proper combustion. Unburned fuel then is allowed to pass into the exhaust system where it can backfire.
Can a bad sensor cause an engine to backfire?
An engine sensor malfunction can also lead to backfires. Take for example a bad mass air flow (MAF) sensor. The engine computer uses this and other sensors to compute the amount of fuel to inject into the engine according to operating conditions.
Can a faulty ignition coil cause a backfire?
The same result can come from a faulty ignition coil, distributor or rotor and cause a more repetitive backfire. Car owners usually forget to check the ignition system at the recommended manufacturer schedule. If necessary, consult your car owner’s manual or repair manual.

What does it mean when Your starter wont turn over?
To us it can be difficult to tell what is ment by “it wont turn over as many use this term to describe a ‘no start’ condition and others use to describe a no crank condition, which to us is the more accurate of the two! So a no crank means the starter is not working.

What to do if your Harley Davidson wont start?
Make sure there are no cracks/leaks in the vaccum line. You have to test for vacuum leaks, they aren’t something you can see as you stated. Also try to find out if you have constant spark at the plug when this happens.
