    Honda Longevity vs. Briggs? Tear down a Honda Riding Mower engine. Compare them. Honda is #1 small engine maker, for a reason. I own a Honda GCV 160 push mower and A Briggs 10hp I/C rider. Briggs always has clean oil since main seal leaks 8 ounces per hour of run time. Both engines get drain and refill every 20 hours of run time.

    Here's my theory as of 19:14, haven't watched further yet. I think that the counterbalance was binding and eventually let go, then swung over, hit the governor, and destroyed it. The resulting debris seized up the engine completely. That's my two cents.

    I thought I'd buy a snow blower last winter. Went to the local shop and after finding an interesting machine I then asked about maintenance. "You have to take it back to us every spring! We're the only ones who can maintain these machines!" It was a MTD ME 66.. I asked: "what are common problems or issues?" He said people would make them go faster and ... adjust TIMING with the governor. I said I have never seen a governor that adjusts timing, just the throttle and rpm. No no no! You're wrong! He asked if I were talking about ECUs on cars... He quickly got uncomfortable and said the shop was closed when I said I did not mean to be difficult, I just didn't understand what he meant. Then he threw me out - SHOP CLOSED, I GOT LOTS TO DO!, but invited the next customer. I hate humans.... Looks like I'll have a guy similar to you fix me up a used Yamaha instead.

    When it was low on oil, the oil was in the moving parts, and there was no oil for the pump to pick up. After it locked up, the oil drained back down, so it looks like it had oil in the case. I've run Kohlers for decades, and never had one problem. BUT, I always check my oil before using, and NEVER run it if oil level is low. Even my 1995 Kohler Magnum 18hp opposed twin still is solid as a rock. All the damage is from "Lack of Oil". I'm 77, and have never had one engine go bad. I've raced bikes, boats, cars with no engine problems.

    Kohler sounds German to me, but I guess, it's the same crap like Briggs & Stratton or Tecumseh. Fortunately times of combustors now coming to their end. Just bought an electric ride-on mower from Cub Cadet and it behaves fine.

    Late to the party, but I'd say that having a pressurized lube didn't help in this case, the low/unmaintained oil pumped the crankcase dry which is why the bottom of the motor had issues while the top looked fine. I'd guess the lower counterbalance took out the upper, and then hit the usual, a Mustie1 investigative case! :)

    Well I was looking for boat hull restore info and I find this vid that has nothing to do with boats. Well I have lawn stuff for parts or repair. So i find myself riveted to this video and here is why. I hate videos that sensationalize, monologue to much or can't hold the camera still or drown out the sound with some crazy too loud background music. Also hate that lots of vids have no point or just don't know anything but brag about themselves.. So this guy does an informative video that completely makes true sense of things right before your eyes and ears. So well informed, so thorough, so comfortable and easy to watch. Answers so many questions and makes you feel like your at your friends shop helping him figure out what happened. So now I am informed, learned plenty and gave mustie1 a thumbs up and subscribed. Mustie 1 should be teaching tech schools. He doesn't brag so I thought I would do that for him as in reality it should be. Give credit where it's due and dont brag. Put it in your resume'. Thank you Mustie 1.

    Definitely over engineered like most of the German crap. After all, it's a friggin one cylinder engine. Probably weighs too much as well. Typically lawn tractors don't get their oil changes at proper intervals, therefore no good reason to use nylon parts within such and engine. Nylon gets eaten quickly by the abrasion of dirt.

    Early courage 18 and 19s had a few very common failures. 1. Upper sump bolts back out and the locator pins beat the block out around the cylinder causing oil leaks and eventually block failure. 2. Balancer failure, most often it beats the back of the block out, fist sized hole. 3. Governor gear failure resulting in overspeed damage.

    That's not a Command engine, it is a Courage engine. When you took it apart, I'd be willing to bet that at least one of the cover bolts under the flywheel was loose. They were introduced in 2008, and were plaqued with problems, especially bolt torque retension. Once loose, crankcase vacuum would drop, causing excess oil consumption through the breather. Also, if the engine was stored for extended time with fuel, the carb may have stuck wide open to blow the engine up.

    The long bolt is not a bolt at all it is a pen and that little sheared off Bolt actually killed that pen in place but was sheared off causing the boat to drop to the bottom of the pan and the piece you thought is a bearing is not it's a gilde plate but when the pin drop down the two pieces of the counterbalance come apart causing gravity pull down on the lower one making the gilde plate shredding it and making it off center causing the governor to fall out of its flotation and being crushed by the counterbalance I imagine he made quite a bit of noise for the 10 seconds it was hammering

    Without seeing the video, ... yet... I bet the crankshaft broke. Typical on the Kohler Courage engines I've see. I've had a couple that looked like someone used a die grinder inside the engine. More shattered pieces than one could imagine. That engine series is way too problematic to repair. I just replaced an engine on a Cub Cadet that had 140 hours on it. That isn't much time! It wasn't the governor either that let go on this one. Nothing salvageable left on the one I had. The one I had did have many holes in the block also. I got the tractor for free. I replaced the engine with a Briggs. The lawn tractor looked brand new when looking at it. They have counter balance problems. They just blow apart. I had bent bolts all over inside it. That's what this one had. After the new engine, I parked it on my front lawn and sold it.
