Reef Runner Posted August 19, 2008 Share Posted August 19, 2008 I used to be able to go to the John Deer web site and print out schematics for my lx188. Well now I can't seem to be able to do that. Currently my rider shuts down after about 30 minutes of running it. I think i need to put on a new carb, or at least try to clean it out. Any one have any ideas?

efgh Posted August 19, 2008 Share Posted August 19, 2008 I think your problem is one of the safty switches, there are two, one under the seat and one on the mower switch. If either one of these is bad they will cut the voltage to the magnetic shut off on the bottom of the carb. and cut off the fuel supply. The one under the seat you can jumper across the two wires after it is unpluged to check if this switch is the cause of your trouble. Or as soon as the mower stops check for electric power where the wire fastens to the magnetic switch on the bottom of the carb. There is also a plastic moguale on the left side of the engine that gets soft and mushy from engine heat that will shut the engine down. Hope this helps.

Down2Earth Posted August 20, 2008 Share Posted August 20, 2008 Nothing sits like a deere. It seems like every other John Deere has the same problem. Here is the possibilites that aren't mentioned above.1. Possibly the vent on the gas cap is clogged. You can try removing the gas cap to see if the problem goes away or clean the vent or replace the cap.2. Delay module $153. Ingition moduel hope it's not this one because it's expensive right around $300 I believe. If it's this trade it off a get something that's made to last. This doesn't usually happen till after many hours. A good dealer will let you try out the part to see if this is the problem. 4. Carb/overheating problem5.fuel filter or your tank filter not sure if the lx has a tank filter.6. switch module flywheel 7. water temp module (if liquid cooled)8. bad safety sitchIf it's not any of these I have some other ideas for yah.

Down2Earth Posted August 21, 2008 Share Posted August 21, 2008 If it does happen to be the ignition module i have seen someone before take a magnify glass and find the sodder connection that is broke and re-sodder it and it worked great. Link to comment Share on other sites More sharing options...
Down2Earth Posted August 31, 2008 Share Posted August 31, 2008 reef did you get her fixed yet? Link to comment Share on other sites More sharing options...
Reef Runner Posted September 2, 2008 Author Share Posted September 2, 2008 No luck yet but I think I have it nailed down. I have noticed that my fuel filter empties real quick. I also have some sort of over flow valve on the carb that gas leaks out of. I have been told that it might be my float in the carb. well I am not the best at taking stuff apart and then get it back together again but I think I am going to give it a try. I still am not sure if I am going to try to re-build the carb or just replace it. That is why I would like some diagrams of it so I might have a shot in heck of putting it back together right. I am going to tare into this week. Link to comment Share on other sites More sharing options...
Down2Earth Posted September 3, 2008 Share Posted September 3, 2008 Yes you might have a hole in the float. If you do it will fill up with gas and sink and the fuel will flow consistantly. I have brazed (sp) these many times. But i wouldn't think it would run good for a while and then quit if this was the problem. But I've been wrong before.

Down2Earth Posted September 3, 2008 Share Posted September 3, 2008 Reef if you have a "Good" dealer just go to the service tech and he will give you everything you need in diagrams. Link to comment Share on other sites More sharing options...
Reef Runner Posted September 3, 2008 Author Share Posted September 3, 2008 Well I got the carb off last night. LOL Good luck getting that back on!! Hopefully I won't have to many problems with it. I took lots of pictures incase I forgot what spring went where and what thingamado went into what thingamahole. I did find the HSOforum that had the schematics I was looking for. So that is a good thing. Today I am going to head down to the local dealer and see how much a re-build kit is verses and new one all together.
