Checked oil level on Honda tiller, Fuel in the oil sum
Honda Rotatiller - Model 401
Unit serviced at dealer after sitting for 15 plus years. Carb needed to be serviced, and unit idled rough, but otherwise ran good. After using in garden for about 5 minutes, unit smoked quite a bit, then would smoke occasionally (blue/white smoke). I've drained out oil now and it appears to be contaminated with fuel and does not have oil like consistency.

Re: checked oil level on Honda tiller, Fuel in the oil...
It's hard to say without personally seeing it, i'd change the oil and see if the problem persists. Note that you should most likely use a synthetic mix if you're unsure of the type of oil used previously. Also when filling these units with oil they should actually lay face down, the gas tank on the ground, with the oil level up to the bottom lip of the access hole. This is a common mistake because most people fill the oil while it's in an upright position.

I had a similar issue. Tiller starts and runs for 20 secs. or so then dies. Found the problem! In turning the tiller on its side to check model numbers etc. the fuel line had shifted inside the tank and was stuck just about at the TOP of the fuel level. When I gently pushed the fuel filter and line back to the BOTTOM of the fuel tank, the tiller now runs beautifully! So, check that the fuel line placement inside the fuel tank is correct.
Hi and welcome to FixYa, I am Kelly
This may very well be as simple as having to make sure the generator is sitting level and the OIL level is fully serviced. The generator has a low oil level sensor. The Subaru / Fuji Heavy Industires EH and EY series engines seem to be very sensitive to oil level. I can tell you from owning one myself and from my 40 years of experience. I replaced my oil level sensor and in a few weeks was experiencing the same problem all over again. I finally disconnected one of the wires from the low oil level sensor and resigned myself to checking the oil and servicing the oil to full each time I added fuel. (It works for me)
There are other things that can cause this symptom. Without your exact model number I can not look it up and make other recomendations at this time. If you still have the problem first try disconnecting ONE wire from the low oil level sensor after making sure the unit is fully serviced with oil. Then see how long it is before it shuts off. (If at all!) Once you disconnect the low oil level sensor you MUST check and service the oil if necessary each time you add fuel.
Should the problem persist respond here with a COMPLETE model number and I will help you.
Pull off the float bowl. Clean the bowl and bowl nut. Also in the threaded are where the bowl nut screws in there is a fuel jet / orifice with a tiny pin hole in it. If you have a inlMake sure that pin hole is clear of debris. Pull off the hose going to the carb and make sure you have good fuel flow to the fuel manifold. If you have poor fuel flow check the in line filter and the fuel tank exit port for debris. Use carb cleaner to clean fuel passages. With the float bowl remove the the main fuel line disconnected shoot carb cleaner from the float needle to the fuel hose connection and then from the fuel hose connection to the float needle. Reinstall the main fuel hose, float bowl and nut. Check for leaks BEFORE switching on the ignition.
Additionally make sure the engine Oil is serviced correctly. There is a low oil sensor that will kill the ignition if the oil level is low. For trouble shooting only you can disconnect ONE wire and check spark. If you did not have spark with the oil sensor connected and you have spark with it disconnected then the oil level sensor is either working correctly sensing a low oil lovel or... it is dirty and needs cleaned.
This SHOULD get you up and running again. If not just respond here with your ENGINE number and I will help you
If this is the LNU25 style engine it has an oil capacity of .08 Liters of oil which if not very much. If someone tipped the engine for cleaning or installation of an accessory you can get oil in the cylinder. with the ignition OFF, clear the oil by squirting either carb cleaner or fuel into the cylinder. Make sure to pull the engine through rapidly with the spark plug removed to clear out cleaning agent. Then clean the spark plug, reinstall the spark plug and re-service the engine oil level. Start the engine and let run until warm. When finished using the tiller and the engine is once again cold inpsect the oil level and the cylinder for oil once again. I think you have a one time incident at the moment. If the symptom happens again prior to your next use just respond here and I will help you.
Remove the Oil Breather from the side of the engine near the base of the valves and clean it with both engine degreaser and carb cleaner. If the reed assy sticks on the breather the crank case will over pressurize and port oil into the breather. Also if the engine was over-serviced with oil it will present the symptom you describe. Sometimes a carb problem will allow fuel to leak into the crank case after sitting for a long time and the oil will have gas in the oil. Sniff check the oil. If it smells like gas you may also have a sticking carb float or float needle.
If you need more assistance just repsond here and I will help you.
Honda has an oil level switch. It is possible that the switch is faulty or there is not enough oil in case. Check oil level also smell the oil to see if it smells like gas. If you have gas in the oil this problem can occur also. You may need to change the oil.
Oil normally comes out of the air filter area a little bit, but over time, once the oil rings start to wear, more and more oil comes out. So you can either have new oil rings replaced, or you can put in a crank ventillation valve in there and it often helps slow down the oil from entering
Yes that could be the problem. I would pull the spark plug and spray some carb cleaner or gas into the cylinder and try to start it. If it runs for a few seconds then you have a fuel flow problem, possibly a dirty carb.
Gas has ethanol in it now and ethanol attracts water. It can also break down certain types of materials that are in gaskets, fuel lines, etc. that gas does not affect. This can cause clogged carbs and the water can cause corrosion in the carb and other areas. It's a good idea to add a fuel stabilizer (even Walmart has these) to your gas especially if your gas powered tools tend to sit for long periods of time.
I would certainly consider taking it back as you should not have to deal with problems caused by old gas if you purchased the unit new.
Most likely the carburetor jet is still clogged after sitting for years with fuel in it. Putting injector/carb cleaner in the fuel tank may help, but if not, the jet needs to be soaked some more -- or replaced.
Follow mixing proportions on the label for injector cleaner.
