Kohler 7000 series engine trouble shooting

The fill plug is on backside of engine, dip stick is on front. Page 3 page 8. If the carb float does not shut off you need to replace carb, this will stop fuel from flowing and into engine oil.

Ron, Try new plug/s first, sounds like the carburetor has dirt in it, you will probably have to remove carb. and clean/rebuild. From manual, other causes from your trouble shooting guide ,
? Faulty carburetor. ? Faulty cylinder head gasket. ? Faulty or misadjusted choke or throttle controls. ? Fuel pump malfunction-vacuum hose clogged or leaking. ? Intake system leak. ? Loose wires or connections that intermittently ground ignition kill circuit. ? Quality of fuel (dirt, water, stale, mixture). ? Restricted fuel tank cap vent. Check the attached links,instruction and guides, Good luck

plugged fuel filter or fuel line?

Could have blown a seal however before checking for that I would check the drain plug and filter seating if you changed the filter. Make sure the drain plug is not cross threaded. You can run a little low but should never over fill. Hope this will help. Most of the time if over filled you will get some smoke as well.

Sounds like you have oil in the gas galleries of the carb. Fill it with gas turn gas valve on and try starting it a few times with starting fluid to help rince/thin them out so gas can flow through them again. It may smoke more than usual for a while. Dont keep it running on the starting fluid though as it has no lubrication for the cylinder/rings and could scar the cylinder walls. If that doesnt work you can remove it and try to do it manually with a can of carb cleaner or get a new carb. They're on ebay for about $20 or a small engine supllier near you will have one for about the same or a little higher.

Check for spark at spark plugs then check fuel and fuel filter .

Troubleshooting a small Petrol engine that won't start requires a series of short tests and the process of elimination.
Understanding the principles of how a small engine operates is helpful but not necessary.
Proper disposal of hazardous liquids will be required.
The knowledge gained in the performance of this procedure can be applied to many different types and sizes of internal combustion engines.
The average weekend mechanic can complete the process in about an hour.
Put on the safety glasses.
Remove the gas cap and check that there is gas in the fuel tank.
Look at the inline gas cutoff valve located below the gas tank on the fuel line and make sure it is in the on position, with the knob turned straight in line with the fuel line.
Look at the spark plug and check that the wire is securely plugged onto the plug.
Try to turn the spark plug by hand and make sure it is screwed firmly into the hole.
Look at the ground strap by the spark plug and make sure it is not touching the spark plug.
Look at the kill switch located by the controls and make sure it is in the run position.


Remove the air filter by unsnapping its box-like cover or removing the wing nut that holds it onto the carburetor.
Lift the air filter out of the holder and set it aside.
Spray a shot of starting fluid from the aerosol can into the empty air filter area of the carburetor and try to start the engine.
Let the engine run about 30 seconds or until it dies.

Eliminate the electrical system as the cause of the problem if the engine started right up, ran a few moments, and quit.
Remove the gas line from the carburetor by loosening its hose clamp with the screwdriver kit.
Hold the fuel line over the clear glass container and let some gas run into it.
Look at the gas, checking for water and impurities.

Drain the gas tank if the gas looked impure.
Remove the gas filter from the fuel line by loosening its hose clamps with the screwdriver kit.
Replace the gas filter with a new one if the gas did not run into the glass at a rapid pace.
Reinstall the gas line and gas filter.
Fill the gas tank with new gas.

Find a small drain bolt located on the very bottom middle of the carburetor.
Place a small container that gas won't melt under it and remove it with the wrench kit.
Let the old gas drain out of the bottom until the new gas starts to flow out. Screw the drain bolt back into the bottom of the carburetor.

Clean up any spilled gas off the motor and elsewhere with the shop rag.
Place the rag in the metal bucket a safe distance from the work area.
Clean the air filter with warm, soapy water if it is the spongy type, or replace it with a new one.
Install the air filter. Start the engine.

Unplug the spark plug wire from the spark plug if the engine did not start.
Hold the insulated part of the spark plug wire with one hand and place the bare part about 1/4 inch away from the top of the spark plug.

Try to start the engine and watch for a spark between the wire and the plug. Replace the spark plug wire with a new one if it shocked you through the insulation.
Remove the spark plug using the spark plug wrench and replace it with a new one if there was a spark.
Try to start the engine. Let the engine run until it performs smoothly.

Do not do anything else if there was no spark, as the trouble is inside the internal workings of the engine and requires professional repair and tools.

check you oil level and see if gas has filled up the engine. Drain and refill oil. Test again. If working order a carburetor kit or fuel shutoff valve from www.arcolawn.com to prevent it from happening again.

good luck

Sheeesh 3yr old gas is'nt gas any more, drain the tank and fill with 93 octane add injector cleaner. change spark plugs. Be prepared to charge battery. Good luck!

Hello, oil to use in the engine depends on engine if it is a Kohler you will want to use 10w30 approx 2qts. The Briggs & Stratton engines use HD30 or SAE30 approx 1.5qts. Use the dip stick to ensure you have the right amount and don't over fill.

To change the oil:

• run engine about 10 minutes to warm up oil so it flows better

• at the bottom of the dip stick there is either a valve or plug
  

• open the valve or plug and let the oil drain (I use an old gallon oil container with a funnel) leave the dip stick out
  

• while the oil drains; change the spin on oil filter

• once all the old oil has drained replace the plug or close the valve

• wipe down the funnel and use it to refill the new oil

• use the dip stick to ensure proper fill level

I also recommend that you replace the air filter at the same time, if the engine can't get air is can't run efficiently.

If this is helpful please vote yes, Thank You!!

After sitting for 2 years, the gas has moisture/water and it's pretty much not gas anymore. It's like your car needs 87 octane and you are running on 80 octane, just enough to fire off but not strong enough to to keep a good idle/firing. I would drain all the gas out and use a higher octane gas for a half of tank just to clean the lines and injectors. Fill the tank up 1/2 with high octane and use a bottle of injector cleaner. This should clear up the sluggish problem. Also it's a good idea to change the oil and run an engine cleaner through. Drain a quart of oil, and pour in the engine cleaner. Let engine run for about 5 min for oil to heat up and circulate. Drain oil and change oil filter, put in new oil.
