Craftsman Riding Mower Won't Start

I have a Craftsman LT1000 and it will turn over, but never starts. It sounds like there is no compression. There is oil is in the cylinder. Could my piston rings be bad?

Had old lawnmower that would not start. Went to Oreillys auto and purchased start my engine under $7 dollars. Poured half in, it started and runs fine. It was a back up mower attempted to start it for the last 3 years it's a Toro so I did not want to throw it away. Main lawnmower ran with a shake so poured the other half in it, mower runs smooth. Might not work for you, but is not expensive little work (do not have to remove old gas) and cheaper than paying someone to look at first. Good luck.

Craftsman Riding Mower Won't Start

I have a 42 inch, DLT3000 Craftsman that won't start. The motor turns of and all I get is a back fire? I tried jumping the safety switch under the seat and it still does the same thing.

Craftsman Riding Mower Won't Start

I have a Craftsman riding mower, model 91720512, 6 speed, 42 inch cut, 14.5 Briggs and Stratton motor. I have replaced the ignition switch and starter solenoid. I was cutting grass yesterday, it was running fine and after running for about 1/2 hour, it just dies like if you get off the seat and safety switch killed it. I turned the key, no click, no crank, obviously no start. It was late so called it a day.

I checked today and thought I found the problem with a loose white crimp connector going to switch for clutch. It has a 4 pin block connector that plugs into clutch switch that clips into frame, 2 white wires and 2 black wires. I repaired the connection, nothing! I checked and replaced 30 AMP fuse, looked OK, checked battery voltage, fully charged 12.6 volts, checked wires for seat safety switch, they look OK. What next? Please help. My lawn is like a jungle! Suggestions to fix today?

I think you may have an open ground. I have a John Deere with the same problem. I have yet to find the open ground. This is how I have to start my mower. I have a battery booster. I hook up the postive clamp of the booster to the postive side of the battery and the negative clamp to a metal part of the mower bypassing the negative battery terminal. The mower starts right up. Then I have my lady shut off the booster and unhook the clamps. If I get off the seat you know the safety devices shut down the mower.

I need to know what to check to see why my Craftsman riding lawn mower won't run. We have checked the battery, the starter, and the plugs. It does have a little fire, but it will not turn over.


Why won't my Craftsman Riding lawnmower start? It keeps flooding. I already tried letting it sit and drying out the filters.

RE: Craftsman Riding Mower Won't Start

I take it the coil is producing a good spark? Might be good to replace this and also try to physically check that the motor will turn by hand. If you have movement, and the unit turns then it should start when it has a good spark. On failing that I would have the carburetor overhauled. Hope this helps.

The float in the carburetor is probably stuck and it needs to be serviced. (07/21/2009)

I have a Craftsman riding mower. When I start it, it runs about 20 minutes and then shuts off. I try to restart it and it won't start. What do you think might be the problem?


I have a Craftsman 18.5 hp riding mower, why does it barely start? The starter struggles to turn the motor. It will turn 1 or 2 times, then it's like it locks up, then it may take 3 - 4 tries, then will finally start.

My Craftsman riding lawn mower won't start. It isn't getting a spark. I think it's the safety switches, but I don't know how to check them.
