Sears Riding Mower Won't Start?

My rider won't start. I replaced the filter, plugs, and fuel pump. It's not getting gas. Any ideas? If I put gas directly into the carb it starts for a few seconds. The gas lines are clear.

Have you tried to clean out the injectors yet? When you pump the gas is it going into the gas lines. What I mean by this if you try and pump the gas and remove the gas line from the carburetor do you see gas coming out of the lines? If not then there is an issue with the lines being plugged or you are having an issue with the new fuel pump not pumping the files through the lines. Have you tried to prime the fuel pump to get it pumping the fuel?

I've got gas to the carb. So filter, lines, and pump are good. I took apart the carb and sprayed with carb cleaner.


If I put gas in the carb with funnel it runs for a couple seconds. Spark plugs are ok.

That's a bummer!
Why did you decide to replace all those 'parts'?
Your mower would not start or would not run?
Have you been able to use it this season or had trouble from the beginning?
Did you put mower to bed last year with gas in the tank? If so, did you add any kind of gas storing additive?

If old gas you need to remove gas and use only new gas. You will need a Siphon Kit for removing gas. These are sold at Walmart or any auto parts store.


If you go to an auto parts store then you may need to also purchase a can of starting fluid. This is to spray into your carburetor to get it started and maybe clean out the fuel jets.
Also - if you did not replace the air filter (you just said 'filters' so gas? or?) this would be a good move.

You can discuss your problem with someone at the auto parts store and they may have some additional solutions to try.

These lawnmowers are very temperamental. I hear so much going wrong with them.

Best take it to a shop.
