Hi, mower wouldn't start, checking the plug it appeared dry so replaced the carb (diaphram looked poor). Now will start once for a few seconds sometimes but then not again in the same attempt. Plug appears wet when removed but engine will not even fire once after priming like it did when fuel starvation was the problem. Any ideas what the check next?

A Dirty Carburetor Can Cause a Lawnmower To Start Then Die

By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.

A dirty carburetor is the most common cause of a lawn mower that starts and then dies. Other possible causes include: Stale/Dirty Gas. Faulty Choke.
If your lawnmower starts up but then dies in the middle of mowing your lawn, you could have a bad spark plug. The spark plug works with the ignition coil to create a timed spark in the cylinder, causing combustion. The spark plug is really a very simple device.
If your mower loses power and then won`t restart, it might be due to dirty air filters. This is a simple problem to check and fix. Make sure the filters are clean and in good working order and try again. If this was the problem, it should start up again easily.
If your lawn mower starts, runs briefly, then dies these are the four most common reasons that`s happening: Dirty carburetor / clogged carburetor bowl. Old gasoline that has gone bad. Dirty or defective spark plugs.
Use Carburetor Cleaner

Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.

Your lawn mower runs for 30 minutes then dies if you are having issues such as a bad spark plug, air problems, a malfunctioning carburetor, or a faulty gas cap. You may even encounter the issue that your lawn mower runs for 5 minutes then dies.
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the engine for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
If a mower is hard to start, it may be the result of a dirty carburetor and/or a clogged air filter. Use a screwdriver to remove the carburetor and clean any dirt out of it with a rag. Clean the air filter or replace it if it`s disposable.
Other things that could cause this issue are bad fuel, weak/colapsed/kinked fuel line, faulty spark plug, faulty ignition/coil, oil over full, clogged air filter, plugged/dirty carburetor, worn engine parts internal rings/valves/etc.

Self propelled mower will start but want stay running long? it runs about 3 or 4 min. then stop and when i restart it, it will start back up.
ANSWER : The fuel bowl has a float and needle, if the float isn’t floating to open the needle for gas to flow into the carb, it will cut off. A kit can be purchased for about $5 or take yours out and soak and clean then replace. Usually when these go bad its best to replace them.
