Whats going on everybody! Today I’m working on this Honda mower that hasn’t been run in a while and won’t start up. So I’m going to take you through the steps that I use to diagnose a non-starting small engine. First off, lets take a look at the oil and see if there is anything in there. That dipstick is dry as a bone, so we will need to put in some oil before we try to start things up. There, that looks a lot better. Then check to see if there’s any gas. Now its time to try and start the engine. Let’s check the easiest thing first. Make sure you don’t have any obstructions in your air filter that would block air from coming through. In, my case there was just a roach, and some roach droppings, but I have found cardboard in these before…. Don’t ask me why someone put it in there though.

I am SO happy I came across your video! I had cleaned the carb, checked everything, and thought I had gotten the Magneto cleaned from the surface. Nope, pulled it and the center contact had rust on it. Cleaned reassembled and it fired right up! Not bad for an old lady! THANK YOU!!!

Newer Honda lawnmowers, use an auto choke system. If the engine does not start while cold, but it starts well when hot, the thermowax cartridge, located in a hole on the side of the cylinder in line with the choke linkage may have failed. If the cold engine starts and stays running using carb cleaner when you spray a shot into the carburetor to prime it, you will know that this wax cartridge has failed and needs to be replaced. It is a "thermowax" 16620-Z8D-305 part from Honda. A good thermowax will have the little probe retracted when it is cold. Conversely, a failed thermowax will have the probe stuck extended while cold, holding the choke butterfly open. So the engine is starved for fuel when cold. The probe in the thermowax moves the choke butterfly open when hot and closed when cold.

Good point, George. Problem with mine staring cold was the thermo wax cartridge. Replaced and now starts first pull. Damn things are expensive, $30.00 on Amazon for a genuine Honda part.

@fdkrew 6 ай бұрын

I saw a video of a guy getting a manual choke system and by passing using the thermal wax mechanism. I’m thinking of doing this to my Honda tired of it failing at least 3-4 times a year.

I have a Honda mower and I love it! I clean the spark plug at the beginning of the season, check / replace the air filter and clean the mower after each cut. After about 15 + years it’s still going strong. No issues with it so far.

Backfire is when the engine fires back up the intake, after fire is when the engine fires through the exhaust. This can be caused by improper valve timing or a rich or lean mixture

Another thing those Honda engines are good for after they've been sitting awhile is no compression. Then you have to pull the valve cover and remove the intake rocker and unstick the stuck intake valve and it'll have compression again.

I have one of those. So far I have replaced all the wheels, both rear wheel adjusters, the carburetor, all the cables except the throttle cable,and now the transmission and axle. I hope this thing is worth the effort. The front wheels are supposed to lock up but the cables were frozen. It was $66 just to replace them. I only paid $35 so I pray it doesn't need anything else. The transmission cost me $145. I normally just part them out but committed myself to repairing this on . I have another with a badly bent crankshaft that I plan on replacing. Honda mowers are over complicated for what they are. Those drive shafts are trouble. Every one I got refused to go backwards. Usually it's rust on the axle. Honda needs to get its act together.

To clean the jets and air passages, you need to remove them and clean them manually with small wire or carb brushes. Then spray everything thoroughly with carb cleaner. An ultrasonic cleaner works great with carbs if you have one.

Worked great when i tested it out and worked great an hour later at our house. That's when i noticed there is no Primmer Bulb at all and that is kinda important. Hoping the one at Lowes for $6.29 will suffice! Not sure if thats all it will need but the filter is pretty nasty too. Wish us luck, our yard is gross.

Just so you know, to start these Honda mowers with the flywheel brake, you have to engage the blade when pulling on the rope. I noticed that at 1:08, the blade was not engaged when trying to start the engine. Sure, the blocked carb and choke mechanism not working would've prevented it from starting, but not engaging the blade will also not start the engine either.

Great video, Thanks. However, My issue is a little bit different. Just went to start my 25 year old Honda 214 model ( I believe) Had started it every year, and ran for about 15 minutes. However, for the past 2 did not. Brought out yesterday to start and service, and starter cord would not pull at all. Tried moving blade underneath, but remembered there is a blade brake/clutch or similar devise in place. Just trying to free piston. Note mower always kept in air conditioned/heated garage, never out in elements. Also, always ran carb dry . Any suggestions to free motor would be great. When it ran, it was just fine. Thanks Robert TN

@kachiquitaito3341 2 жыл бұрын

Sometimes when lawnmower hit something hard get stuck and won't pull the cord or kick back the handle cord front the hands and blades not moving or hard to move with the hands. You can try moving the blades move the blades with a long wood and if you thing is a divice or cluth stopping the blades you can try put the handles in running position but be careful this is only to check if the blades move a little to free the piston.,

Yes, but every time you stop the lawnmower that break comes in contact with the flywheel and shaves some of the pad off. Over time it seemed these pieces accumulated behind the coil, this the reason for no spark.
