I was going to post this in the John Deere section but it doesn't seem anyone has posted there since last year. I hope to get some answers in here. I have googled my problem but haven't found any good answer.
I have a JD LX 176 w/ Kohler 14hp engine. Last year it didn't want to start. The engine would have to spin over for a while before it would start. It seemed to be worse when it was hot. It would also backfire out of the intake and the exhaust. I mean a really loud backfire, sounded like a shot gun.
I mis diagnosed it as a valve problem. Took the head off, lapped the valves, new head gasket, adjusted the valves and it still did the same thing. It sat all winter and today I decided to mess with it again. It started up twice and ran fine. I had the valve cover off it still so I shut it off and put it back on.
I tried to start it again and it started doing the same thing. It will spin over and will eventually backfire. I have an inline spark tester in it and it is getting spark.
I know that it is capable of running because it did it twice.
I have read it could be the flywheel key or some part of the ignition system. The coil was replaced last year but didn't make a difference.
I've been working on cars for 15 years now but these small engines seem to give me fits.
Any help would be greatly appreciated. The grass is growing and my wife is wanting to know when I'm going to fix this thing.
Any help would be greatly be appreciated.
