Servicing Small Engines (Honda GX25 and GX35)

This video is about how to change the oil and air filter on the GX25 and GX35 Honda engines. I demonstrate how to drain the old oil and fill the engines with new oil. For the air filter service I show how to remove the old filter and then clean and oil it before reinstall.

Just bought that exact tiller here in the states for half off since it was missing the air filter and the plastic cover. Thanks for the tips on care.

I use honda whipper snippers for my landscaping business and they are amazing, got an old one that runs like a champ. Some of the Stihl ones are great as well.

I also have a gx 25 weed trimmer and i love it. That 4 stroke sound is sooo nice😂

My grandfather has had this model for like 20 years. Never been serviced. Been hard to start for the past year and now I can't start it at all. I think the motor might be locked up. I checked the oil and it's dirty but not sludged up. They're good engines I might try and get it running again with a proper tune up.

Far out, wish I would have seen this when I got my first UMC425. I don’t think I was filling it all the way, it was going to 3/4 to almost to full length of the dipstick, but I reckon it was running a bit hot for sometime filling it that way and just had it seize on me recent. I was changing it once a month as I run my own garden maintenance biz, but I reckon I wasn’t filling it properly, which was overheating it. Thanks for this, will be doing it right for my new one now.

The spark arrester is fairly easy to access too for the GX25. Just a 3mm hex allen key to remove the red plastic housing and a phillips head screwdriver to remove the 2 screws securing the arrester housing plate. Surprised how dirty mine was for only 15 hours or so use. The spark arrester is kinda spot welded to the housing plate so not sure if using the blow torch method to burn off the carbon is safe but I just used some long nosed pliers over my gas cooktop to burn off the debris, don't think I damaged the metal housing.

Very informative video.Excellent.
Can you see any reason why I shouldn't hang my Lawn Edger (GX25 motor) rather than keep it stored on the floor.

Great info. most helpful. Unfortunately no one has air filters in thailand; sell only. no parts for service. Assume i can clean; wash air filters

Great vid, I have many brands of trimmers and the Honda's are my go too, as they are 4stroke they work well at low speeds around sensitive areas such as trees, pots, mesh. The 2strokes are great for other jobs that is for sure.

How many days should the oil be changed?
