Small Engine Repair Honda Won't Start?

Another thing to check that I did not mention in the video is some engines like this one has a low oil sensor and if the oil level is not high enough the engine will die and not start.
It doesn't matter if you have a Harbor Freight predator engine, a nice Honda, Tecumseh, or Briggs motor they are all set up the same with similar components. This videos shows some of the main causes for your engine not starting. Since its getting cold you'll want your snow blower or generator to start right up. Since this is a small engine it will work for your go kart, tiller, pump, generator, snow blower, mower, edger or whatever you have in your garage.
Here are some simple tips to check and if those don't work it might be the carburetor.
1. Check gas
2. Check on/off switch
3. Check spark
4. Check oil level
5. Check carb.
I've been working on small engines for about 20 years and almost every time an engine has been sitting over winter the carburetor is gummed up and needs to be cleaned.
Hope this video helps someone out. Good Luck!

UPDATE:1 year and still cranks within the first 2-3 pulls. Probably will buy another when this one finally does bite the dust ru-vid.comUgkx43QMbQqu67IZadu9ou8Sg1BdrunMRNqX . No issues at all. Very happy with it.UPDATE: After 6 months of use and over 70 uses I would still highly recommend this pressure washer. It does vibrate a decent amount but never had it “walk” like others have mentioned. No oil leaks, still seems to run like the day I bought it. Still cranks within 2-3 pulls every time. Very happy with my purchase!Have used it about a dozen times now. Plenty of power, cranks up on 1-2 pulls every time. My only complaint would be I wish it was a little taller to make it easier to walk with it (hits my ankles a lot) and that the two hose connections were a little further apart but it hasn’t caused me any issues. Seems to run a good 1-1/2-2 hrs on a full tank, overall a well built machine and definitely worth the money in my opinion.

@deangrande7207 2 года назад

Other than cleaning your carburetor and you’re still not getting fluid how do know , when to just swap out carburetor with new one?

@-DIYPRO- 2 года назад

If you test it out with some starting fluid and it starts up then dies then you know for sure its the carb and you can replace it. If you shoot carb fluid into the carb and it still doesn't start then it's something else. Check spark plug, check oil level (some small engines have oil level sensors that cut the engine out if low oil)

@MegaFlaxman 4 года назад

MegaFlaxman I hope I can get a response on this question. I have a 2008 Honda clone 6.5 horizontal shaft. It was in the original box till just recently when I aquired it. I filled with oil and gas and wouldn’t start. I checked the compression and it’s 28 psi. Checked the rockers and they’re moving like they should. I removed the rockers and physically moved the valves up and down, both seem to be seating properly. Filled cylinder with oil and tried again, still 28 psi. What’s my next move, remove the head and check the valves?

Then fuel is not getting into the bowl. With the bowl off see if the float is opening and closing (it's the plastic donut looking thing). It should hang down and be letting gas enter. Then if you push it up it should close off. Those get stuck closed and open all the time. I wish I could post picture in comments to show. Hopefully that makes sense.

@-DIYPRO- 2 года назад

Mine is currently covered in snow or else I'd go double check but I'm pretty sure these have a low oil sensor. That would be my next check. Double check that it has oil and that it's level. I say that because I had a tiller once that tilted the engine slightly and so even though it was full on the one end it was actually low on the senor side and would always shut off.

When i tested for spark... it lit my light spray off fluid. Hard for my eyes to look for spark... but easy to see a 2 second fire! (I will actually purposely use this method in the future!). Secondly, my single bottom bolt to the carb bowl supplies the main jet! I used my torch tip cleaner kit, dupray, and comoresser air... she fitted right up! Fresh gas, a bit of mystery oil... and my freebee pressure washer is on its way for use!

Hi there! For winter storage should the choke be left on the on or off position?

@-DIYPRO- 2 года назад

Choke doesn't matter. Important part is to either run the carb bowl dry or if you have a fuel cut off switch then turn it off so no fuel goes into the bowl and run it til it shuts off. the killer is ethanol fuel sitting in the bottom of the bowl. It will separate and gum up the ports.

This video allowed my gx390 to once again crank up and run. It turned out to be the ignition coil. Quick question - I bought my pressure washer (4k/4gpm - gx390 this engine) and after 2-3 pulls it will crank but it takes a little muscle to pull. The pressure washer pump is removed and I made sure the engine is not vapor locked by changing the oil and also removing spark plug (pulled a few times to rotate it). What would cause the pull to be pretty hard? I know this is a bigger engine but what could it be?
