I ran into one last week on a briggs and stratton single cylinder. It actually broke the flywheel. I've been repairing lawnmowers for about 12 years and this is the first time I've seen this happen. Great video. Keep up the good work.

Very nice fix. Some of the earlier models did not have that ground connection on the voltage regulator and when the bolt failed to ground it , you had to add a short ground wire. The Kohler Courage engines are even worse, many issues and crankcase leaks, carburetor issues etc. Thanks for the video, Great work.

A blown head gasket most of the time would not make a popping and missing sound. It would sound like air puffing out when you turn the key to the off position while engine is slowing down. If the flywheel key is ok? It will normally be ignition, try replacing spark plug, carburetor, rebuild it or possible a valve issue but valve issues are rare with the Kohler command engine.

Thank you for the very informative video, it helps alot when people do tutorial videos to exclude the annoying music! And it helps the viewers when you do speak the commentary! I have this same exact mower, I've had it since 2010. Bought it used at approximately 300 hours. It now has 537.6 hours. I'm just now starting to have issues with the motor, the deck/mower parts I've replaced as needed over time. My issue with the motor is the last time I mowed (I have 1 very rough terrain and dusty acre) I was approximately a little more than half done when it made a pop sound (sounded like it was internal and wasn't very loud) it had been smoking for a bit but once it popped it started getting sluggish. So instead of pressing on thinking that it blew a gasket or piston ring I just shut off the engine for fear of it locking up. I let it cool down went back and tried to crank it. All it did was turn over but no start. Next day tried it again and same thing! This was 3 weeks ago, I had a friend of mine that is small engine literate come take a look. He first tried the spark test ( gets excellent spark)then pulled the valve cover (all looks good). He then took the cover off to expose the flywheel and checked for compression (all good). He ran out of time because he was in the process of moving to a new place and had to go get a key and would be back to go deeper in to find the problem when he had time and I had money to pay him! Lol. He did say that it could possibly be a carburetor/choke/solenoid issue??? He then said if that wasn't the case then it would have to be internal (my guess is full motor rebuild???) To my knowledge this motor has never been opened up but we did find that there where a few small rocks on top of the fly wheel where the fins are??? But none of the fins are chipped or broke! Could I have sheared that flywheel pin??? Or would it be a best assumption to try the carburetor/choke/solenoid first??? On a normal mowing routine this motor does smoke for about the first 3 or 4 laps then quits. I have noticed that it does burn oil it has to be because I dont see where its leaking or puddeling, It stays parked on concrete???

@JohnsonsSmallEngines

2 жыл бұрын

I would pull the flywheel and and check the key before getting into the carburetor. You said it started loosing power after the first pop. A sheared flywheel key will make the engine sluggish because the timing will be off.

We think it might have broke the piston arm!😥😫☹ So if thats the case then that would mean that the motor ran without oil but that doesn't make any sense bcs I know for a fact that it had oil every time I'd get ready to mow! What would cause the use of so much oil to burn that it would run itself dry within the 1 1/2 hour mowing time??? We haven't actually dove in to the guts yet, that will be our next investigation. Probably today! Also since I bought this mower used 10 years ago it doesn't have a service manual.

@@kevinbrister8801 There are many different reasons why your engine can burn oil. I can say that most small engines do burn a little oil while running and if you went a very long time without adding it or changing the oil and oil filter? It can run low and lack of lubrication will happen, then boom the connecting rod will break. Which in your case may have happened. Not much to do now. Repair it or just fine a used engine and install. You should be able to find a service manual online. Just google Kohler Command Manual PDF and many should pop up. You may need to enter the model of your engine that should be on the silver sticker on the side of the engine to get to the correct manual. One manual may also cover many models.

Thanks for the great video. I have popping on one cylinder of a 24hp twin B&S. The push rod was off on one cylinder which seemed obvious. Put it back in, adjusted the valves to .04 and problem still occurs. I'm assuming a sheared key would affect both cylinder's performance. Could this be a bad valve adjustment still or possibly a bad ignition coil on that side? The popping gets worse with time (seems to run fine for 30 seconds or so) and gets worse, fairly quickly. The valve head on that side also seems hotter than the other side. thanks for any ideas.

If the push rod was out of position. Check to make sure it’s not bent, then you need to find out why it happened? Check the rocker studs to make sure they are not loose. Checked spark on both cylinders at the same time with two inline spark testers to make sure your ignition is ok. Check valve lash again. Install a new set of spark plug. If it still is popping and missing, you may have a valve seat came out of place and the only way to check is to remove the head to see. You may also have a valve guide that worked its way up but that doesn’t happen often.

Correct, on the single cylinder Kohler command engine there is no adjustable valves. They have hydraulic lifters. I can say that sometimes the valves will sound horrible “loud tapping “ noise until the lifters get pumped full of oil. If your experiencing loud valves? Run the machine by cutting grass for ten minutes then listened your engine and it should be quiet by then. Also make sure your using 10/W/30 oil and it is at the correct level.

Thank you! This time and most I have seen are from a loose flywheel bolt. Belts will give before the flywheel on tractors. I’ve seen a lot of sheared flywheel keys on walk behind mowers where the blade is connected to the crankshaft and the blade stops dead and the flywheel will keep rotating to shear the key.

I have the exact same engine and found this video very helpful. Thank you so much for taking the time to share. Can I ask how you lost your hand Sir ?

I pulled the flywheel off the key was good.. two of the magnets on the flywheel were broke free.. has a new coil new battery fuel is okay

What would you say the actual torque would be for the crank bolt?

@JohnsonsSmallEngines

You should look up your engine model to make sure you are getting the correct torque value. The correct torque for the engine flywheel bolt in my video is 49 foot pounds.

Does it run? Perform simple first. Install a new spark plug, check to make sure carburetor is 100% ok, check the choke and throttle plates on the carburetor inside to make sure they are tight on the shafts. Other than that you only have the valves that would make the popping and missing, you would need to tear into it to see what’s up like a valve seat loose etc.

@@cravenmoorehead5636 Doubt it. The next step is to take head off. You may have a valve seat popped out but I cannot confirm any of what you have done without seeing it so good luck and keep on working in it until you find out what has happened.

When I run at full throttle, and engage the blades...the engine will run at reduced rpms for about 15 minutes. Then the rpms go up to where it usually runs as if by magic. It will stay perfect for the rest of the mow. But on the next mow? It does the same thing again for about 15 minutes. Would you have a good idea where I should start looking? Thank you, in advance!

It sounds like the throttle plate inside the carburetor may be loose. OR Governor needs to re-adjusted. I would check ther carburetor first.

I believe mine was caused by a lean carb causing a backfire. This propelled the crankshaft too fast and sheared the key to the flywheel.

If you have a ignition spark tester? Check the spark after installing a new spark plug. If you have no spark, disconnect the ground wire from the ignition coil. Check for spark again. If you do not have spark. You have a bad ignition coil. Replace ignition coil.

It’s running lean (lack of fuel). See if it will get better compensation with using the choke. If it gets better using the choke, you need to rebuild the carburetor.

@@JohnsonsSmallEngines Thank you! Would a sheared keyway under the flywheel give similar symptoms or just a no start popping. Wish I had oem carb. It came with an Amazon special and I bought another new to try as well. I suspected fuel too but from tank to carb is all new including fuel lines, filter and shut off valve. 🤷🏻‍♂️

I would pull the flywheel if it isn’t to hard for you and check the key. Also check to make sure the fuel is flowing good coming out of the fuel line right before the carburetor. If the flow is good then it will go back to what I said about the lean condition in the carburetor. I tried a aftermarket carburetor one time and it did not work and now I only use OEM on the Kohler command engines or try and rebuild them first. You may be able to find a good used OEM on eBay or purchase a blown engine that would be cheap that may have a OEM carburetor on it.

You should NEVER hammer on the crank shaft. You would be amazed the microscopic damage that occurs on the bearings, which will reduce the life of them.
