Question about Garden
I have a John Deere D140 lawn mower and the engine will not start. I charged my battery and everything looks normal. Please, any suggestion?
Does it turn over/crank well?
Did you check to ensure you have fuel and that it's getting to the carb? (you can simply pull the hose off the carb, and crank the engine holding a little glass under the hose to see if gas pumps out)
Did you check the fuel is not rotten (it should be clear and smell like gas at the gas pump, if it is orange or has a bad smell it needs to be replaced)
Did you check the spark?
Did you check for water in the tank? This looks like little bubbles floating on the bottom of the tank because the water and gas don't mix and the water sinks. Any water at all will contaminate the fuel. You will have to drain the float bowl, the fuel lines, and the tank, dry them and put in fresh fuel.
Did you clean the carb float bowl? If the fuel you by has ANY ethanol content and the tractor sits more than a few weeks without running it is very common to get gunk build up in the carb that will block the jets and keep it from running. carefully cleaning it can fix this.
Tip, do not let carb cleaner get on any rubber seals as they will swell and not fit properly anymore. (or just by new seals)
Check these and repost findings if it doesn't solve your problems, good luck!

>>From your Description it Sounds like a Carburetor Problem, a Bad Fuel Filter or Bad Gas.
>>If you have Changed the Filter and the Gas and the Problem is Still happening, then
>>The Following is a Simple Way to make Sure the Engine is Getting Gas from the Carburetor to Run.
>>If the Engine Starts and Quits, then Check the Carburetor Solenoid.
>>If the Carburetor Solenoid is Good or has been Removed and the Engine will Start and Quit when the Gas is Poured into the Carburetor Throat, then Soak and Clean the Carburetor.
>>The Following is a Basic File I Made for Cleaning Carburetors. Any Input is Appreciated. Even though the Carburetor Looks Clean, the Internal Passages May be Restricted with Varnish that Gas Causes to Build Up over Time.
>>Spray Cleaners Remove this Varnish in Layers, so Soaking is the Only Sure Way to Remove ALL this Varnish.
>>I have Found that Most People can Use a Breakdown/IPL and Disassemble the Carburetor Enough for Proper Cleaning.
>>You Only have to Remove the Bowl (if Applicable), Float Pin (if Applicable), Float (if Applicable), Needle Valve.
Remove Any Adjustment Screws that Go Into the Carburetor Body. The Welch Plugs Do Not have to be Removed.
>>If you are Able to Remove and Disassemble the Carburetor and Keep the Gaskets Intact, then Usually these Gaskets can be Reused. The Only Parts you May Need to Replace is the Needle Valve.
>>The Float Needle Usually is Not Replaced Unless it is Not Operating Properly (the gas flow not shutting off and the carburetor is Flooding). Do Not Remove the Main Nozzle. This is a Pressed Fit and Removal is Not Required for Cleaning. Soaking and Blowing the Carburetor Out After Soaking will Clean the Nozzle.
>>Once Disassembled, then Soak the Carburetor Body and Parts in a 1 Gallon Can of Gunk Carburetor Cleaner Overnight. The Can has a Parts Tray Inside it for the Small Parts.
>>Once the Carburetor and Parts are in the Cleaner, you can Replace the Lid for Safety and to Prevent Accidental Spillage. Then Blow Out the Passages with Compressed Air.
>>***(Do Not Use High Pressure Air for the Zama Carburetors, they have Check Valves for the Primer and these are Usually Blown Out of the Carburetor if Not Careful. Allow the Zama Carburetor to Set on a Drip Pan and Dry)***.
>>****All the Carburetor Adjustments are the Same for Lawn Mower and Trimmers. There are Several Location for the Air Mixture Screws. The Idle Air Mixture Screws are Usually Located at the Top of the Carburetor Bowl and the Top of the Carburetor Body.****
>>If the Main Air and Idle Air Mixture Screws are Side by Side on the Side of the Carburetor, then the Idle Air is Nearest the Engine. The Main Jet Air Mixture Screw is Located in the Bottom of the Carburetor Bowl or Beside the Idle Air Screw on the Side of the Carburetor Body.
>>Some of the Older Model Carburetors have the Main Jet Mixture Screw Straight in from the Top of the Carburetor Body (this is Rare anymore). If you have Cleaned the Carburetor (Disassembled and Soaked Overnight in Carburetor Cleaner (I Use Gunk). Then Blow Out the Passages with Compressed Air and Install a New Kit if Required. Now Setting the Air Mixture Screws:
>>****Turn the Idle Air and Main Air Mixture Screws In Until SNUG **Do Not Jam** Then Reverse Both Screws 1 1/2 Turns. Holding the Throttle Full Open, Start the Engine. Turn the Main Air Mixture Screw Clockwise Until Proper Revs are Obtained. Occasionally you May have to Turn this Counter Clockwise to Achieve the Proper Revs. Now Allow the Engine to Idle. Set the Engine Idle Screw (Not Idle Air) so the Engine will Stay Running if Required. Now Set the Idle Air Mixture Screw so there is No Hesitation when Throttling from Idle to Full Throttle. Reset the Engine Idle if Required.****
>>If This Carburetor has a Single Air Adjustment (Except Tank Mounted 9200 and 100900 Engine Model Carburetors), Use the Section Above that Pertains to Full Throttle RPM Air Mixture Screw and then Adjust the Screw if Required to Eliminate Any Hesitation when Throttling from Idle to Full Throttle.
>>For the 9200 Model Tank Mounted Carburetor Adjust the Air Mixture Screw Full In, then Reverse 1 1/2 Turns. Set the Throttle Lever to Full Throttle and Start the Engine.
>>Now Carefully Use 1 Finger and Open the Throttle Plate and Over Rev the Engine Slightly. If the Engine Over Revs and Does Not Struggle to Over Rev, then the Carburetor is Set. If the Engine Struggles to Over Rev, then Turn the Adjustment Screw In 1/4 Turn and Repeat the Over Rev Test.
>>If you Adjust to 1/2 Turns In and the Engine Still Struggles to Over Rev, then Return the Adjustment Screw to 1 1/2 Turns Out from Snug and Turn the Screw Out 1/4 Turn. Do the Over Rev Test. Continue this Process Until you have the Engine Over Revving without Struggle.
>>By Adjusting the Carburetor on this Style Carburetor Until the Engine Over Revs without Struggle, you have Adjusted the Air Mixture to the Best Possible Setting.
>>This file was Intended to Give you the Basic Carburetor Cleaning Instructions and May Not Reflect Your Carburetor Components.
>>If you have Questions, Please Ask. The links above Provide Good Directions on Cleaning the Carburetor. Make sure you use an Compressed Air to Blow through all the Carburetor Passages to make sure they are Clear.

Locate voltage regulator above battery to the left as you sit on machine,its behind frame that supports steering wheel.Once you have found it use a light to shine on harness and follow the brown wire that leads into regulator.The plastic around that wire should not be burnt or showing any other color.The LX series machines had a problem with brown wire coming loose and causing the charging light to stay on.Remove plug from reg and use small screwdriver to clean out wire and work it a little so it makes good contact.

Check the brown wire feeding your voltage regulator,its between batt and steering wheel behind left side of frame.LX100 series machines had a problem with brown wire not fully contacting terminal in regulator.You will know you had bad contact if plastic is discolored.
