A little help? Lawn mower won't run...

Sounds like it is starving for gas. It is using up what gets through the filter and then dies. It will eventually pull enough through the filter to start again. Replace the filter, then run the appropriate amount of Seafoam (or Power Service) through the gas tank.

I'll try the Seafoam. But I use gas with no ethanol. Also, I have a Cub Cadet with a Honda engine that I've never had any problems with. I also have an Echo weed whacker that I use gas from the pump with no issues. In other words I don't think ethanol gas is the problem. I agree there may be some dirt or clog but the air filter is clean. Thx for the help! Can always count on the forum! Will report back.

That, or the gas tank breather hole is clogged and the tank vacuum resulting after running the engine for a short time prevents further fuel flow to the carburetor.

I pretty much always forget to drain or run out both the Honda lawnmower and the Honda snowblower.

The simplest fix is nearly always just to removed the drain screw/bolt from the carburetor bowl, let the old gas drain. Then apply the choke and start.

The one time that did not work, I used a bit of spray starting fluid to get things going.

Take the carb apart and clean it. I handn’t used my lawn mower in four years and left it with gas. Honda engine. Used carb choke cleaner to spray the carb. Everything looked good, drained gas and checked fuel line. Changed oil and spark plug. (Filter,Oil,Spark plug) Kit cost $16 at HD. Pulled to start it would run for less than a minute. Watched a YouTube video on cleaning carb. Took carb off and cleaned it. It was plugged up like crazy. Put it together and all is good. Next was the line trimmer. I ended up just ordering a carb off amazon for $12 and new fuel lines for $10. A rebuild kit was like $5.

We lived in rental that included lawn care. After two years in my home, with a lawn care guy. He decides to raise the rate and my youngest son is 15. Wife is like “it’s time”.

Edit: if you can get the bowl screw off the bottom of the carb (10mm bolt) and spray some choke cleaner through the top orifice... probably easier to spray in the bolt hole to clean out the main nozzle. That would be the easiest way to clean any obstructions from the carb.

Remove the spark plug and see if it's dry or wet. Dry, no fuel is getting to it.

Wet, it may be fouled or that gas got old and lost its spark. If the plug is gas fouled, fresh gas and cleaning it may help. Or the plug may need to be replaced along with the fuel.

Dry, you'll probably have to clean the carb and fuel lines.

You should probably test to see that there's some spark getting to the plug, but that may require some help.
