What Will Cause A Riding Lawn Mower Not To Start. If the gasair mix isnt balanced the engine wont start or the engine will run rough and stall when you try to drive the riding mower. Tap the side of the carburetor to help the flow of gas.
When your air filter becomes completely plugged with dirt and debris your engine will not start because it cant draw air through the filter. For a few dollars this easy fix can get your small engine working again. The reason fuel causes problems is that some fuels are ethanol-blended fuels like e10.
My lawn mower battery drains after 1 or 2.
You said not to start but I dont know whether you are asking about starting it or something else like why it doesnt run while its running or something. Other possible causes include. If something causes any blockages in the fuel flow the engine will not start. Your mower should start within three pulls of the starter rope unless equipped with a Quick Start engine.
