The mower was starting fine then all of a sudden it wont turn over. It tries then floods out. the battery is fully charged when try to jump with vehicle it wont turn over. Do I need a new starter or could it be something else???
Your valves need adjusting.
SOURCE: I have a briggs and strattan 18 horsepower engine
Set intake valves @ .004 and exhuats @ .006 with piston a 1/4 inch downstroke from TDC.It sounds like the ACR {automatic compression release}is not working do to valves having to much lash.
SOURCE: mower won't start
im sure the switch is bad, trying to jump is a good way to find out if the starter is bad but of course wont start cause of no spark, alot of these have electronic magnetos

Replace the float, sometimes they get saturated and look fine but are'nt. Also clean out the jets and bowl. The needle and seat may be worn as well. In other words, rebuild the carb. This time of season, after the equipment has been sitting all winter, I rebuild 25 or more carbs a week. It should cure your headaches, and solve your problem.

Hi,
My name is Dane and I'm going to help you with this. I need you to do a couple of steps for me, and one involves using a voltmeter. You can pick up a cheap one at a hardware store or auto parts store. They will even show you how to use it if you need them too. It will come in very handy around the house and well worth the $15.00 you will have to pay for it. Put your battery on a charger while you get the meter so it will be fully charged later. When the battery is charged, remove the charger.
I want you to set the meter up for Volts DC and (With the engine OFF) place the red lead on your battery positive terminal and black lead on the battery negative terminal. If your battery is charged ok, it should be around 12 volts.
Now, I want you to start your tractor, and check the voltage again with the engine running. Do it the same way you did with the engine off. If you are getting around 13.5 - 15V, your mower is charging and you probably have a bad battery. Check your terminals and make sure they're clean and tight. If you got the same voltage with the engine on as you did with the engine off, make sure the electrical connectors coming out from under the shroud of your engine are all connected. I've been doing this for a while now and I've never had a stator go bad yet. Not saying they won't, but it's very rare. To change the stator, which is actually like a car alternator, you have to remove the top cover of your engine and pull the flywheel off. It's normally bolted to the top of the engine block under the flywheel. If you come back and tell me the stator's bad, I'll tell you how to do it. But for now, I think you'll have enough information to get back running again.
Just a note. Those stores which use the resistance type battery testers. The ones that Glow red when they test your battery. They can't really properly test your battery unless your battery is fully charged to begin with. Amazing how much money they make on that little "FREE" test.
Ok, if you have any more problems with this, just add a comment on the bottom of this post. I hope I've helped! Thank you! Dane

If the mower starts and continues to run after injecting, you may want to make sure the choke is working properly. If the choke plate is not closing all the way, it will make cold starts difficult.
Testimonial: "thanks for the help the choke was open just a little"
