Bought it from a local dealer and planning to take it back.

Bought it from a local dealer and planning to take it back.

that would be the smart thing to do, I was thinking you bought a new mower without a warranty like buying a chinese John Deere?

UPDATED:

1. I've looked over everything and do not see any loose wires. Disconnected some of them and reconnected.Still no start.

2. I don't have the right socket for removing the spark plug so I'll have to tackle that later today. The spark plug is going to be a bit hard to get to. Thanks to Briggs and Stratton on that one. How common is it that a brand new riding lawn mower has a bad spark plug?

3. Would the engine make any kind of distinct sound if the flywheel and/or fw key has an issue?

4. How common is it for the the anti-afterfire solenoid to be a problem on a new tractor? If the solenoid is a problem, would the engine turn over at all.

5. If the flywheel and/or flywheel key were damaged would the tractor turn over but not start? Last time I used the tractor everything worked find. I used it to get up a lot of leaves. I drove the tractor in the garage when I was done. Absolutely no indication there was a problem. However, the smell of fuel was pretty strong. Still, no indication there was a gas leak other that the smell.

Appreciate the responses. When I resolve the issue I will post the solution. I'm finding plenty of posts online regarding this problem but people rarely post if/how they fixed their tractor.

1. That is good.
2.It is very un-likely that the plug is bad... but that May be a problem.. (can check later)
3.No, not necessarily. if the key shears you May notice a change... Or not, just depends on where the timing moves to...
4.If the solenoid is working, You May hear or Feel it click when you turn the key switch to n/run position. The engine will turn over with or without the solenoid...
5.The strong smell of gasoline, MAY be an indicator that the solenoid did Not close wwhen you turned the engine off... Check your engine oil level... is it over full, or very thin like it has gasoline added to it? If the solenoid fails to close you can get raw gasoline flowing from the tank through the carb and into the engine, ending up in the oil..... all this fuel in the engine can give a strong fuel smell, and flood out the cylinder & spark plug, preventing it from starting or even turning over at times.

Do follow up with your 'solution' Your right, there are some that do not post back with "the Rest of the story..."
Don't give up... you will only get to know your equipment better by following through with this & any future problems...

Even If the dealer discovers the problem... Please post back what it was...:smile:KennyV

UPDATE: Talked to Deere and located an authorized dealer closer to where I live. Unfortunately they are closed today. I replaced the spark plug this morning. Still wouldn't start.

What percentage of fuel should I be seeing in the fuel filter when I try to start the mower. I usually see 5-25% fuel. Is that normal? should it be more like 50-75+%?

You should get a good flow of gas at the carburetor. I know what you are saying about your fuel filter. The fuel filters have like a air pocket in them. Just thinking on mine they would run more like your 50-75%. I just never paid any attention what was normal.

I have attached a pic of the fuel filter and old spark plug.

My fuel filter always looks like this, even on other pieces of equipment. I've manually filled all of them to the top and have never allowed them to run out of gas, yet somehow that air pocket gets right back in there. They seem to run just fine this way, so I don't worry about it any more.

I'm an avid DIY'er, but I'd take it back to the dealer.
