Features of use and maintenance
Honda GX Series general-purpose gasoline engines ranging from 98 to 688 cc can be found on almost any type of small machinery.
Control
There are many modifications of the Honda GX - some units have controls on the engine itself, others place them in the center of the remote control, usually on the handle of the unit.
The main controls are located on the carburetor, which is located directly under the air cleaner housing. Some Honda GX series models have a throttle lever at the very top almost on the air filter housing. On some models, there is a fuel valve underneath it.
The throttle must be set 1/3 way from Slow to start. On models with a lever on the body, move the lever to the left to open the throttle. The throttle should be closed if the engine is no longer warming up and the fuel valve should be open.
On Honda GX electric start models, the engine is started by turning the key or switch to the "Start" position. After 5 seconds, if the engine fails to start, release the switch and wait 10 seconds for the starter to cool before trying again. If the engine will not start, turn the switch to the "On" position. and use a recoil starter.
Checking the oil and oil level sensor
The oil dipstick is integrated into the oil filler. To check the oil level correctly, the dipstick must be wiped off and then inserted into the engine without filling it back into the filler neck. When adding oil, the level should rise to the edge of the filler.
Some models are equipped with a Honda oil level check system. It automatically shuts off the engine if the oil level gets too low. If the engine suddenly stops, check the oil level to see if this is the cause. On electric start models, a light on the starter panel should illuminate to indicate that the warning system has been activated.
On Honda GX motors with a gearbox, the gear is in a separate housing with its own oil supply. It has its own filler and dipstick and uses the same oil as the engine. The body should be approximately half full of grease.
Candle fuse
Regardless of the model, the Honda GX engine muffler is designed for use with a spark arrestor. The fuse can be accessed by removing the muffler shield. The arrester itself will be held in the muffler by one screw. To clean the arrester, remove any deposits with a wire brush. If it has any splits or holes, it should be replaced.
Air purifier
Inside the air filter of Honda GX engines, there can be up to three types of air filters that require periodic cleaning:
- Paper items can be cleaned by pressing on a hard surface to chunk away dirt.
- Foam elements should be washed with a mild detergent or non-flammable solvent. Once dry, immerse the filter in clean engine oil and squeeze out excess fluid.
- Cyclonic filters should be disassembled and cleaned. Any dust inside the filter housing must also be wiped off before reassembly.
Gas engines (LPG)
If you have a Honda GX270 or GX390 gas powered (LPG) modification, there are a few differences in handling them.
Since LPG is a gas, there will be no visual signs of leaks.Instead, there is a smell next to the engine. If you find any traces of gas, repair the fuel system before starting the engine.
The throttle lever increases the vacuum to help draw gas into the combustion chamber. After starting, the engine will provide the required vacuum and the throttle can be opened. There is no need to wait for the engine to warm up.
On Honda GX gas engines, use only SAE 30 oil for use with LPG engines or 5W-30 synthetic oil when operating below 0 ° C. Mineral oil can work fine in other GX engines, but will damage the LPG model.
