Make: John Deere

I changed fuel filter and park plug, checked air filter. It shut down while using it.
Welcome to JUST ANSWER small engines, let me try to help you !!
We need to determine if you lost spark or fuel.
Remove the spark plug, and with it grounded , see if you have spark at the plug.
If you do, then put about a teaspoon of fuel direct into the spark plug hole, re-install the spark plug and seeif it will fire for few seconds. If it does, we have a fuel problem.
These two test will tel us what to do next.3
Thanks. Will try that soon. I'm not sure of the paymeht details, but I do not want a membership. Just todays answers. Will be back. Thanks,.
I grounded the plug and saw the arcs. I put a syinge of gas in plug on two occasions. Engine still never fired.
With spark and fuel, and won't fire, the valves should be examined, a push rod can be off, or a valve stuck. Could have sheared flywheel key throwing timing off, but rarely happens on rider unit. I would check the valves, and if plug is still out, see if you have any compression.
