It is about as simple as fixes get. The fuel in the oil is coming from the carburetor overflowing into the intake manifold. If you replaced the OEM carburetor with an eBay carb, your assumption that the needle valve and seat in the new carb will fix the problem may not be good. OEM...

Spinning the engine does not push all of the 'fluid' out of the engine. There is probably nothing wrong with your block and head. The problem is probably with the needle valve and/or seat in your carburetor. Best to replace with OEM parts in your OEM carburetor. In old days, there was a fuel...

Stop while you're ahead before you break something. Call a Kubota dealer and have them come out and get it started for you.

Do a search. You'll find enough to read for days.

I had the same thing happen with a C50 Chevy truck, 350 V8. When I bought it, the seller told me to use Conoco oil or it would use oil. I paid no attention to him; oil is oil. Next oil change, I switched to Quaker State because I had a bunch of it on hand. Just as he said, the oil...

What's the purpose of this thread?

The only angle cut should be on the hinge cut. There are lots of youtube videos showing how to fell a tree, but none using cuts like this. That tree could go either way.

I realize that he was told how to do it, but there is no evidence that he ever did follow those directions correctly. I see posts on page 2 in which he says it was running, but he saw on here that there is a second filter so he replaced it and it wouldn't start, so he cracked two lines (and by...

Broken bolts, stripped threads, or other such things that sometimes happen can blow the flat rate out of the water.

Don't pull a line completely off an injector. CRACK open the line at one injector (not the injection pump) slightly, maybe 1/2 to 3/4 of a turn. Keep the two wrenches on or a close to the injector as you can. Crank the engine until you see fuel begin to leak our of the fitting on the...

You didn't say where you live. I would contact the county agriculture agent and get their recommendation. If you don't have one, I would try this: 1. Remove the top 6" of the clay soil and replace it with black dirt and a sprinkler system. or 2. Deep-till in sand to increase the porosity...

If you're getting coolant in the cylinders, you probably have a bad head gasket(s), a cracked head, or a cracked block. I'd guess the most likely suspect is the gaskets.

Clean the carb again, only better this time. If it runs on starter fluid, it'll run on gasoline whenever you can get the carburetor to send it some.

Many mistakes made here. Best bet is to consult the Kubota manual to see how they recommend changing fuel filters and priming the fuel system, injection pump and injectors.

Compressed air works good for anything that isn't wet.

It could be a QA issue but if you haven't kept the cylinders and heads free of grass clippings and other debris, it might be an overheating issue which has allowed the valve guide to migrate out of the head. Then the rocker arm collides with the valve guide and the pushrod bends. It's not...

It's very important that the airflow over the engine is not reduced and that the cooling fins remain clean. Take off that broken fan housing, clean off the cylinder(s) and replace that broken fan housing with a good one. AT LEAST once a year remove the fan housing and clean the engine.

Most large engines are the same. Some airplane engines are built to rotate the opposite way.

These same people would undoubtedly throw a FIT if someone threw a hamburger wrapper out in front of their house, despite that it poses essentially no risk, while a street coated with grass clippings is about as slippery as ice.

Combining motorcycles and lawnmowers....why do people throw their grass clippings into the street?

My Kawasaki powered Husky MZ52 never fills its clear fuel filter. I don't understand why not; but it doesn't and it runs fine. I suspect you have a bent pushrod.

Check your valve lash.

Hi, I'm one of the moderators here. You posted two threads about this problem and I tried to merge them into one. Unfortunately, I lost one of them and don't think the merge went off as I intended. I apologize for that. In the future try not to post duplicate threads in different forums, as...

One of your basic assumptions is wrong. As circular items, such as the rod journal, heat up, the inside diameter gets bigger, not smaller. So let's consider other things that could lock up your engine, which was running fine right up to the point of being shut off. I'd take off the shroud and...

You need to activate the blade brake at the same time. But that will take more than just electronics.

If I'm not mistaken, gasoline will do the same thing to styrofoam.

Find a diesel repair shop around Lebanon who can test injectors. It's probably only one of the three that's bad and it can probably be repaired. No guarantees, but diesels are not something you want to start throwing parts at. Too expensive for that. FWIW, black smoke means too much fuel...

Our wonderful government, saving the environment one pilot screw at a time...

Take out the spark arrester screen the in muffler and see if that makes a difference.

So you think turning an engine upside down causes valves to go out of adjustment??

Post pictures, history, price and location. That should help.

First thing I would have checked are the injectors. Missing and smoke sounds like bad injectors.

It might be. Getting turned upside down may not have helped the needle valve in the carburetor. You might need a new needle and seat but you still need to keep the fuel shutoff valve closed any time the generator isn't being used as a precaution.

Does it have a fuel shut off valve and if so do you keep it closed when the engine is shut off?

You couldn't have done anything to the valves by rolling it over. If you've had it running, there is no liquid remaining in the cylinder. If it has rubber engine mounts, did one of them break when it fell?

I would walk the whole thing, maybe even dragging a magnet behind me. The reason I give this advice is because when we bought our property, I didn't walk it. I was VERY careful mowing it the first time and hit nothing. For the second mowing, I put the wife on the tractor and she hadn't gone...

You may find it while mowing and this time there might be a loud 'bang.'

Exhaust Open, Intake Closed. Set the Intake when the exhaust valve just starts to open. Set the exhaust valve when the intake has just finished closing. E-O-I-C

Sorry for being blunt, but if you have to ask for help finding the valve covers, you probably should not be adjusting the valves.

There are TWO TDC's--One is when the exhaust valve has just closed and the intake valve is just opening. You do not want to set the valves using THAT TDC.

Does the Rotella T6 5w-40 not have the 1200 ppm of zinc like T4 has?

Rotella T6 5w-40.

I have no idea what MS 1909 and 2004 are, so this may be of no help to you at all. I'm running Windows 10 and Firefox as the browser. Have been for quite some time. IIRC, when a new version of Windows installs, it installs Edge or Bing but you can choose whatever browser you want. If at all...

The gap is related to bore diameter by a number called 'pi' which is approximately 3.14159 A .00314159 change in gap indicates that the bore has changed .001" So, roughly a 3:1 ratio.

^^^^^ This is good advice. If you're not going to be the one boring these cylinders, you really don't need any of this stuff. If you will be the person boring cylinders, you should already have a good grasp of what machinist tools are needed and how much they cost.

Yes, PRICE is usually a good indicator of tool quality unless you run into someone selling knock-off tools for nearly-full retail. Then you've paid quality price for junk. If you're going to buy quality tools, buy them from a vendor. Brown & Sharpe, Starrett, and Mitutoyo are good brands...

If the engine doesn't have an oil filter, I'd change the oil after the first five hours, then annually if no more than 50 hours are are put on the mower per season. If you don't have an hour meter, you'll have to estimate how many hours you're using the mower per season.
