Batter was dead, i jumped many times to mow. Last time it it died while mowing. i changed battery, checked spark, turns over good but won’t fire? could i have burned out the alternator or magneto?
Experienced gardeners share their insights in answering this question :
Hello,
I can see no reason for your Alternator to be blown, Unless you connected direct onto your alternator which would solve nothing.
1/. Check your Battery Terminals are Really Tightened, next check out the most likely which is normally under the Dashboard your Fuse box.
2/. Should your fuse box be all working then it has to be the cables or the connections to the magneto, get the magnet checked!
3/. I think your problem is on the Fuse Box. It would help if you could give me the age of this Machine. Best Wishes, Malcolm.

Description – KOHLER ENGINE OIL

SAE-30 is an acceptable substitute if temperatures are above 50°F, 10°C. K-Series and Magnum engines should use SAE 30 (Magnum Oil) above freezing. 5W-20 or 5W-30 can be used in all engines when temperatures are below freezing.

Kohler recommends 10W-30 oil for its engines, including Command, Command Pro, CS, Courage, Aegis and Triad OHC engines, when the piece of equipment is in an environment where the temperature is above 32 degrees F.
The John Deere Model L tractor was a small one-plow row-crop tractor produced by John Deere from 1937 to 1946.
The serial number of a John Deere tractor can, however, be used to determine its year. The 10-character year symbol is included in the 17-character Vehicle Identification Number (VIN) used by John Deere to identify vehicles. The year of manufacture of your tractor is stated in the VIN`s tenth character.

Kohler engine 15.5 turns over but will not start
ANSWER : Hi hoho641…

Make sure you are getting spark at the spark plug, to do this:Remove your spark plug and check to be sure you are getting fire at the spark plug.You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting spark then:
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible. Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one.Make sure you are using fresh fuel.If the moweris over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.Be sure to mark the turns down on a piece of paper.That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
After you have the carburetor rebuilt that should solve you starting problem.

No spark at plugs after replacing coils it has spark advance what do I look for next
ANSWER : Check for the switching pulse at the coil input terminal. It should be less than the battery voltage but not zero, or pulsing in sync with the engine (if you know the spark dwell angle, you can calculate the voltage by multiplying it by the number of cylinders, dividing by 360 degrees, then multiplying by the battery voltage). If you don’t get any indication that the coil is being switched to ground to generate the spark, your distributor contact (for mechanical ignition switches) , magneto or electronic ignition module could be the problem. Before changing whatever one of these you have, double-check the wiring to the coil – a misplaced, broken or loose wire will have the same effect.

Oil leaking out on yardman mower – Yard Man YardMan 11A41K3001 21Inch 173cc Kohler OHV Gas Powered BagMulchSide Discharge Lawn Mower (NonCARB Compliant) ()
ANSWER : You haven’t supplied a lot of information but generally when this happens it is due t the mower being tipped the wrong way.
If you must look under the mower then tip it back with the handles to the ground and front wheel in the air.
Now to rectify your problem; The air-filter will probably be saturated with oil. It will probably be the cartridge type which is not serviceable. Purchase a new filter (take your old filter so the sale person can compare like for like). Before you refit the new filter, take out the sparkplug, it will probably be saturated in oil – wash it in petrol, let it dry then refit it. The engine should start and belch out great quantities of smoke. Don’t be alarmed this will burn away. Once the smoke has cleared, check the oil level, fit the air filter and mow your lawn.
