lawnboy1022 It sounds like it may have jumped time. To check you can use an ohms meter and have some one attempt to turn flywheel very slow while connecting one lead to spark plug wire end the other to ground. Turn flywheel watching when the contact on flywheel comes to position with coil you should see meter move? Also pulling engine cover look close at key that aliens flywheel if it appears it spun even a little that should be the problem!

My only intention in my posting is to maybe help the next person along in their search of a lawn tractor or learn a bit about them for myself. Whether it be green, orange, blue, red or black. I don't think anyone disagrees with the fact that quality is not what it used to be, even with the advancements in technology. I wish, like most other americans out there, that we still manufactured everything here in the states. But that is a long distant memory and will probably never be again. But I bought a John Deere because the one I had before it lasted, and the farm I grew up on had plently of them that did their share of breaking, but got the job done everytime. But so did the Case, Internationals, Massey's, and I think a New Holland. Every manufacturer out there has it's share of problems. Nothings perfect! John Deere has been in my blood since childhood when I played with my first little green toy. Everytime I get on my X530, I will be proud to have one. People don't usually buy Harley Davidsons because of their quality (although I feel them to be very well built). They buy them because of the name that sits on them. If John Deere stops making a good product, the brand would eventually suffer and only be found in the history books and a few landscapes maybe. But when I drive anywhere, it is still the brand I see most often, and usually they are moving. So, drafted 72, your opinion is noted and hopefully a few people may benefit from your experience, but a GT235 and a X530 are a bit far apart in the ways they are used. I have no doubts that mine will still be alive and well in 15 years. And if I have any problems, I will be sure to post them, so the next person at least can use the info to decide if the JD brand is right for them.

Well, I thought this problem had solved itself. The thing started well most of last year and until this week. I thought it had a stuck ring or valve, or a little bit of varnish from the modern gasoline. Anyway, I installed two champion CJ8 s, gapped to .025. And it started right off. Changing from NGK BMR4As Lot's of good comments on this thread. It's a little over my head. I'm assuming that if the composite camshaft gear breaks, it's definitely not going to run, correct? And further regarding this thing, is this gear failure always a fairly benign thing? That is nothing else gets bent or damaged when this thing goes? I had the case cover off to repair the inner gasket to prevent water from leaking into the crankcase, actually I don't think it ever went into the crankcase, but it eventually would not hold water even to mow the yard once. I then, wasn't aware of this issue with the composite gear and I'm not totally sure if it has the composite or not. I seem to remember looking at a brown fiber gear-looking thing. But I'm not sure. Thanks for all the comments, and I think it's just the spark plugs causing this problem. Although I'm not sure why long cranking worked to get it to start. Anyway...Cheers!

This is my first time on here, so I don't exactly know how to post so here goes. My JD-425 has a flooding problem. Sometimes it runs ok, and sometimes not. When I turn on the ignition, the fuel pump starts (as normal) and I can usually start it. Then, after running for a while, it begins flooding. This is between 15 minutes and half an hour most of the time. I can keep it running if I go full throttle and have the tractor under load, like mowing grass, but there is so much gas entering the carb that there is a bit of black smoke as well. If I stop it and remove the air cleaner, and look into the carb, there is gas everywhere. Here is what I did so far... The carb was new 3 years ago. But I removed it, and took it apart (did this 3 times). Each time I took it apart and put it back together, I know I did it right because the machine started and ran as noted above. I thought it just might be plugged or something. The first time I took it apart I also replaced the electric solenoid valve, just to be sure. And I know it works, because I saw it operating with the carb disassembled. Then, I thought it might be that the float valve was leaking or perhaps the floats had a hole and was full of gas. All was good. When the carb was back together, I blew into the fuel hose when the carb was full of gas and proved that the float valve was working. Hmmm. There is a manual in-line fuel shutoff valve, so what I did was throttle it back so that it would take 30 seconds to to let about an ounce of fuel out. Full blast, the pump actually pumps a lot of fuel. This time, I was able to keep the machine from flooding too bad. And was able to mow the 1 acre of grass I have. Today, however was different. It ran for about 5 minutes, then began to act up. I turned it off, removed the air cleaner and looked into the carb. When I turn the ignition switch on, (not engaging the starter) I can see tons of gas coming out of every carb orifice, flooding into the engine gas everywhere. This is without the engine running. The only thing I can come up with is that the fuel pump for some unknown reason has too much pressure behind it. Another wierd thing is that when I turn a sharp corner, under the flooding condition, the flooding gets noticably worse. Any ideas anyone? Is there a pressure regulator somewhere in the fuel pump line? Thanks.
