Kawasaki FB460V wont start

[jakesmurray]

This motor is on a John Deere 112L riding mower. We bought it at an auction for $90, they said it would start, but wouldn;t keep running.iWell. it will not even start for us. I tried to start it as is, and nothing. Then I did the following:
-New spark plug (gapped correctly
-New air filter and precleaner
-New oil filter
-Changed oil with SAE 30
-Took off carb, cleaned it inside and out thouroughly
-Replaced fuel filter
-Emptied gas tank, then took it off the mower and cleaned it really well
-Refilled the tank with brand new gas

Here's what I know:
-It has spark
-It has good compression
-The carb is getting fuel

I can tell you that when it is cranking trying to start, you can kind of hear an abnormal clanking noise- like something is rattling inside the engine. Could that be the problem?

Please let me know if you have any suggestions, as I would really like to hear this thing run. Thank you!

Do you have a number on the compression? it might not have enough?

Check the lash on the valves?

Have you checked the diapraghm in the fuel pump?

If you have comp and spark and it wont start your comp might be there but be low or the spark plug is just not sparking properly under compression. Try another plug

I don't have a tool for the compression, but I will check on the fuel pump. I was kind of curious about that. How do you check the lash on the valves? Thanks

Checking lash is a bit to type out.

I have a pdf service manual for this engine and I'll e-mail it to you if you like. (the file is too big to add as an attachment on this post I guess :frown:

Hope it helps. (end of section 6)

You might need some specialty tools (pending your experience level) but its not too tough a job.

Good luck:thumbsup:

All I need is your e-mail address.

Thanks for the help. I actually found the service manual online, so I will take a look at it and try to adjust the valves if they need it. I'll let you know what happens. Thanks!

Ok I've got an update. I decided to put some gas straight into the carb, just to see if it would start, and it does! The bad news is that it will only run for about 5 seconds, but it runs great when its running. Do you guys think it is the fuel pump, by the way I took it off and cleaned it out inside, all of the gaskets were in great shape. I even tried to hook up an external fuel tank to it, and it won't stay running that way either. I think it needs a new rule pump, but am not certain. Can you bypass the fuel pump, or does it have to be on there? Thanks

i would NOT bypass it get all the parts to get it to how it was in the factory that way it will work the best.
good luck :thumbsup:

Your fuel tank is in the rear of this mower. If you bypass the fuel pump how will the fuel get to the front where the engine is. Now if you just want to bypass the fuel pump you will have to put a fuel tank above the engine and just have gravity feed. You shouldn't need a John Deere fuel pump, any vacuum operating fuel pump should work. You might be able to rig something up just to test it.

You have fuel to the carb but is the spark plug getting wet. Crank the engine over and then take the plug out to check.

Take off fuel line from pump to carb and crank it over see if it pumps fuel. If it does then its fine. Have someone listen at the carb while you turn on the key you should hear a click at the fuel solenoid if it has one on the bottom of carb. If it does not click then its not opening the main jet to get fuel.
