I've always used " regular " unleaded gasoline , 87 octane , in my 5
horsepower Tecumseh engine on my snowblower and my 4 horsepower
Tecumseh engine on my lawn mower
On a 6.5 HP Tecumseh engine, the fuel filter is typically located in the fuel line between the fuel tank and the carburetor. It may be a small, inline filter that can be easily removed for replacement. If your engine does not have an external filter, the fuel system may use a screen within the carburetor itself. Always consult the engine's manual for specific information regarding your model.
NO!2-cycle fuel has the oil added to it. In a 4-cycle engine, the oil is separate. If you use 2 cycle fuel in a 4 cycle engine it would be like dumping 10w-30 oil into the fuel tank of your car along with the gasoline - NOT A GOOD IDEA!NO, NO, NO!!!!!!!!! Use only 4 cycle oil in a 4 cycle and 2 cycle mixed with the fuel in a 2 cycle. Why would you even consider doing this?
If the engine has an oil sump and an oil filler spout, it is a 4-cycle engine. On a 2-cycle engine, oil must be added to the fuel.
If the fuel mixes with the oil it is because the engine is a 2 cycle engine rather than a 4 cycle engine. A 2 cycle engine has no oil reservoir and the engine is lubricated by the oil mixed with the gasoline. Without that oil in the fuel the engine would be destroyed. Now if you are saying that you have a 4 cycle engine and the fuel is getting into the oil reservoir, then I would suspect that the needle valve and seat are defective in the carburetor which is allowing fuel to flow into the intake while the engine is not running. This fuel will flow down into the combustion chamber and eventually end up in the oil pan. The float may also be sticking causing the same thing. Make sure to turn the fuel supply off when the engine is not running.
Only if the engine was designed to run on diesel.
No, absolutely not. You must use 4 cycle oil. 2 cycle oil is only used in a 2 cycle engine mixed with the fuel.
A 2-cycle engine requires a fuel/oil mixture. The ratio of oil to gasoline depends on the manufacturer's specifications for your particular engine.
Look at the engine on your lawn mower. If the engine has an oil filler tube or a "hole" with a cap on it where oil is added to the engine, it is a 4-cycle (4-stroke) engine. If there is no oil filler tube or place to add oil to the engine, then it is a 2-cycle (2-stroke) engine and the oil has to be added to the fuel.
Surging is often fixed by replacing the fuel filter. A simple job and most small engine shops will have the part.
A 2-cycle engine completes a power cycle in two strokes of the piston, while a 4-cycle engine completes it in four strokes. 2-cycle engines are simpler and lighter but less fuel-efficient and produce more emissions. 4-cycle engines are more complex but offer better fuel efficiency and lower emissions, resulting in better overall performance and efficiency.
Manufacturer specs may differ but if the engine displacement is around 30cc or is a 31cc 2 stroke, the fuel to oil (2-cycle oil) should be approx. 32:1. 32 parts fuel to 1 part oil
Cycle the ignition on and off several times leaving it in the on position for a few seconds each time. Four or five times should do it.
