If the mower starts and runs - but is constantly making little "misses" - suspect the plug first of all.
No spark from coil, bad plug wires, or bad plugs.
No, but burning oil will give you bad spark plugs.
having bad spark plugs could effect how the spark sparks and when it sparks. new plugs is never a bad idea
you are not getting spark. this could be from a bad alternator, bad spark plugs, bad spark plug wires, or bad engine coils. The spark plugs and wires are the cheapest so try putting in new ones of those first.
There is no way for us to know that.
Typically, spark plugs on a Bad Boy mower should be changed every 100 hours of operation or at least once a year, whichever comes first. However, if the mower is used in dusty or heavily demanding conditions, more frequent changes may be necessary. Always refer to the owner's manual for specific recommendations based on your model and usage. Regular maintenance helps ensure optimal performance and efficiency.
Bad spark plugs, spark plugs wires, etc.
does it have spark to the plug if not the part you might check would be the coil or the electronic start module probably the latter if it is a newer mower or of ots older then the coil magneto usually dont go bad could be a bad gap between the coil and the magneto if its an older mower could be a bad set of points if its an older mower point gap could be bad spark plug could be bad as I don't know exactly what the lawn mower is doing hard to tell what is wrong
No.
Spark Plugs do not affect your alternator. As long as your engine is running then it should be charging unless your alternator is bad
Spark plugs don't smoke. A bad alternator would cause a dead battery.
Yes. Bad spark plugs, bad spark plug wires and a bad distributor cap are the common causes of rough idling. If it has been a while since you changed these components, do so.
