Hey guys as some of you know i've been battling my 99 troy bilt 25 horse mower, was a simple oil leak but it was the crankcase so I had to pull the motor. I also had to replace the drive belt which was a royal pain. After several hours of work and fustration I finally got it all back together go to start it and all it does is crank 1 time. The starter poops up turns the flywheel 1 tooth and thats it. The battery is fully charged. When I pulled the motor There were only a few wires with clip on connectors and the starter wire. I remember a couple wires being hooked to nothing,1 was a solid yellow the other solid black, I tried grounding the black wire to the frame and no help. Any ideas of what I could of messed up or forgot to do when I put the motor back in? Thanks for any help
Need help figuring out why my mower won't start

I don't know what engine you have but most starter motors have two wires to them. One is a large red wire from the battery and the other is a smaller wire which gos to the starter switch after it gos through a lot of safety switches. Also there is another system that uses a external starter solenoid and that would only have a large red wire to the starter motor.

If you have a volt meter take a reading at both ends of the wire and they should be close to the same reading at both ends when the wire is under a load.

Can you turn it over by hand? What did you take apart to fix the oil leak?

It only had 1 wire going to it I remembered that for sure and yes I can turn it over by hand. I didn't remove anything to do with the cylinder heads including wires and stuff like that just bottom end like pullies and stuff

If you lawn mower has a fuel solenoid on the carb check to see that that is working correctly. If it isn't, then thats your problem.

I dont think the fuel solenoid would cause this.
