SOURCE: my riding lawn mower won't start it has a spark

Assuming " won't start" meaning cranking but not getting fired, otherwise my suggestion won't be valid:Try to put some gas into the carb to see if gets started. It is started then died then gas is not delivered to the carb.

The riding mower has been used in June. Now when I try to start it I cant. I have checked the battery, gas, etc. before trying to start it. What can I do now?Thanks

put gas right into the carburetor and see what happens. if it doesn't do anything then you have a spark issue, if it runs until the gas you just put in runs out then it is a carb issue. sometimes just priming the carb with gas will get it to run again too

23hp kiwasaki cold start winds to long before starting

hello sir, mower will not start or run,runs only when primming, does it have good spark,good compression,or only runs on full choke, are you getting fuel to the engine if not try this,your fuel pump or your carb. is clogged up here is what you can do for a simple repair for the carb,you can remove the air filter and assy, empty fuel tank and clean out tank and line,remove the bowl nut and bowl careful of the gaskets,now spray carb cleaner in the small port holes in the carb steam in the middle of the carb until clean,now spray the bowl nut holes until clean there are three,after cleaning put bowl on the same way you removed it with dip towards front of float,put bow, and fresh gas,you should be good to go,hope this helps.,thank you.~~

Mower only runs two min and quits

Sounds like a blocked or dirty fuel inlet.

Remove the carb bowl and work the float up and down until gas flow improves. Be gentle! Just a little light pressure from beneath and the float should swing up about a quarter inch.

The short run is due to the carb bowl not refilling fast enough to keep up with full throttle demand.

Make sure when you put the carb bowl back on there arent any fuel leaks before trying to run the mower.

Good luck and be careful!

Lawn mower starts and runs until I start pushing it, then it just dies out.

Sounds like the carburetor is gummed up. Short of taking the carb off and cleaning, some good fuel line/carburetor cleaner such as Gumout (available at any place that sells auto oil/filters, etc. Wal-mart, K-Mart, Autozone). Put a bit of fresh fuel in the gas tank and add about 2 or 3 Tablespoons of fuel line cleaner. Start mower and let it run a bit. May run rough, but should clean the carb out unless plugged bad. If this doesn't work, the carb will need to come off and be cleaned. Can be done by the homeowner, but if you are nervous about tackling this job it may be best left to the mower shop.
