- I originally thought the pull start had locked up until i noticed the fuel leaking from the carburettor.
Then i quickly realised the engine was hydraulically looked up due to fuel in the cylinder.
Follow along to see how quick and easy it is to fix with minimal basic tools, and an important must do before you attempt to fire it back up.

Your jokes made me chuckle mate :) Got this fuel lock on a ride on, cheers for explaining how the carb is flooding the engine, will do this tomorrow. Hi from England 🌏
🤣 cheers mate. I hope you get it back up and running 😃👍🏻
Just a note that I recently learned about hydrolocking my engine. When you are removing the old gas from the cylinder by pulling the starter lead, be SURE TO NOT HAVE THE SPARK PLUG LEAD ANYWHERE NEAR A GROUNDED POINT!! The gas/oil mix might ignite due to sparking. Could happen just saying. Learned that from a seasoned tech who must have had it happen in the past. Great video and thanks...
Yes, A Very good point 😃👍🏻 cheers
my honda 4 stroke trimmer locked up. After watching your vid I emptied the fuel and oil tanks and removed the plug just like you showed. I was back up and running in 5 mins flat . Cheers from Qld
That's awesome news 😃. Thanks for sharing 👍🏻😃
Very educative
Thank you 😃
You just reminded me that I already have to change the oil in my lawnmower. 😍👍
😃Good preventative maintenance 👍🏻
Wow awesome my brother from Texas USA 🇺🇸
Cheers mate 😃👍🏻
Thank you so much. This is what I needed to know for my stump grinder with Honda engine !
No dramas, thanks for the feedback. 😃
Thank you so much for this video. I was able to fix my pressure washer after being frustrated at not being able to start it.
That's awesome news 😊👍🏻
Excellent video. I am looking forward to trying to fix my neighbors small engine for his snow blower with this information.
Awesome. Hopefully this is the issue. Please keep us posted 😃👍🏻
nice vid, appreciate it. Neighbor's pressure washer is locked up, trying to troubleshoot.
Best of luck 😃
Great video mate! Lovely to see someone take pride in their work and do things properly. Nice workshop BTW.
Gday deebee😃, thanks mate. You should see the shed at the moment 🤦🏻♂️ It is actually about to get extended. Can't wait. Stay tuned to see me set up my new workshop in the near future 😃👍🏻
Awesome informative video, I never thought of the importance of turning the fuel tap off…every day is a school day !
When I change my oil, much like your method, I get a bit of masking tape and run across the bottom of the engine under the oil plug so to stop oil getting under the engine when draining the oil….that’s my 5 cents worth 😂
Enjoying your content, keep it up 👍
g’day Shane, That’s a good idea😃👍🏻
I’ve never had it happen to me, let alone twice.. But handy to know what to look out for 👍
You must put clean fuel in yours 😃 maybe I need a new system 😂
Nice work brother 👌🏽
Cheers Brent 😃
Thank you for the video truly
And thank you 😊
great informative video mate.
Cheers lads 😃👍🏻
Good tips mate
Thanks mick 😃
Thank you!!!!
Not a problem 😃
Your video was very informative. Im certain I can now repair my prrssure! Thanks!
Please keep me posted 😃👍🏻
@@rustyinspirations Going to the laydown yard this morning. Ill post my results.
I am well tutored. Thank you
My pleasure 😃
I have never had a problem finding my ten mil. I have so many. It's the 8mil I have a premium with..
For me it was always the 13, and now that I'm not working on cars anymore it's always the 5/16
Thanks
G’day Glen, you’re very welcome😃
If you install about a 2-inch pipe in the drain hole with an elbow and plug on the end, you won't have oil running all over the place when you drain it. It will run right into the container. Don't know why manufacturers always put the drain right on the frame like that.
It doesn't really bother me with how often it gets serviced. 😃👍🏻
Good boy with the gloves. Something I do not do, but probably should
Definitely should, I’m the same mate. I need to change my habits😃
Great vid try the tomato sauce lid on the oil bottle never need a funnel again.
Cheers Jason,I’ll definitely do that 👍🏻👍🏻
I like the learning part but I mostly continued watching because of the accent....Mum, I did it for 'me kids' 🤣🤣
😁 cheers mate. At least you enjoy it 😂👍🏻
Nobody can find their 10mm. It's an elusive creature.
🤷🏻♂️😂😂
Took out my plug. She pulled great. There was a bit of fuel in there but very little. Pulled and pulled till she was clean . Put the plug back in and no change. Did this procedure 3 times to no avail when plug goes in she’s locked up.
That's very odd 🤔 I have absolutely know idea. Definitely the right plug? It's not to long and fouling the piston?
Its weird i have Aspen fuel which is good for 2 years in it but it still wont start.
Turned out their was water in the oil after it sat outside lol. I changed the oil and it started right up.
Make sure to cover your stuff with a tarp or pastic bag.
Definitely I Good point to at😃👍🏻
This has happened to me but not sure if it's the fuel though. I will be doing the same to see if it is. I will let you know
Fingers crossed mate 🤞🏻😃. Absolutely, keep me posted
Yep, the famous missing 10mm socket and or wrench. 1:42
😂you know what’s up 😃👍🏻😂😂
Hondas r bad about flooding the cylinder with motor oil if the motor is knocked over even seen the better pressure washer 3000 psi or more fluid lock switch most of the. Time is hydraulic or motor oil inside the pump pressure adjustment that also can seize the engine
Good point😃, yes I have also came across some Honda's with oil in the top end 👍🏻
Mine is froze up.
I checked oil, fine, pulled plug, still cant pull it, checked if pressure of pump, still cant pull.
Sprayed W-10 into Cylinder, now to crank with a wrench to see of i can move it.
This is a Pressure Washer!
G’day mate. Unfortunately a lockup engine isn't always a simple hydraulic lock fix. It could be the pull cord, Or it could be something internal in the engine And sometimes catastrophic. In your instance it could possibly be the pump its self that is locked up. You could test this by separating the engine from the pump to narrow down where the problem lies. 😃
Pull rope on 2-stroke trimmer stuck until I removed the spark plug. Then the cylinder moves smoothly with no resistance. Assumed hydrolock. Drained the fuel and checked the carburetor, but as soon as the plug is re-inserted the problem returns. Any suggestions on how to proceed under this scenario? (By the way, when I checked the carburetor I found the air filter to be saturated with fuel.)
G’day Robert, hmm 🤔 It sure does sound hydro locked doesn’t it. Did you find fuel in the cylinder? Being 2 stroke the air and fuel gets sucked into the crank case on the up stroke, so possibly fuel in there also. You might need to remove the plug again and turn it over while it’s upside down or on its side. Or Evan remove the carburettor to get the fuel out. Let me know how you get on 😃👍🏻
Oh my god this is exactly what's going on with my snow blower.
G,day jake😃 Awesome mate I hope it helped you get it sorted 😃👍🏻
I only get one pull out of mine before it’s locked back up again and i have to take the pull cord cover off and manually spin it back in order to get another pull. Thoughts
Gday mate. Apologies, Your comment sliped through. With out seeing it in person, this sounds like a pull starter issue. I'd say the recoil spring has disconnected or broken
@@rustyinspirations no worries. Mine was hydro locked as well. I think mine had an issue in the valves/springs though bc after i had drained the oil and lubed the piston it was doing what i described before so i took the valve cover off to check how they were moving and the pull cord started acting normal.
Awesome 😃, you've done well. Glad you got it sorted 😃👍🏻
Hello sir my generator olso stacked what can l do to get it running
G’day Nephat😀, I’m not sure mate. It can be really hard to diagnose without looking at it in person 👍🏻
I think I have the same issue, however after draining the gas and removing the spark plug, my cord is still stuck. I can't pull and force gas out of the whole where the spark plug is. Does that mean I'm not experiencing hyrdolock on my pressure washer?
Hi Stephanie, Correct your issue may be with the pull start it’s self.
L
Im not a mechanic so I don't know what you mean when you say bottom end. Is your point that the oil needs changing?
Gday Robert, the bottom end is the crankcase, (everything below the cylinder and piston) The crank case contains oil to lubricate the bottom end. Although after time the oil can become slightly contaminated with a small amount of fuel that makes its way past the piston rings. In this case it was exssesive, to the point it had actually increased the oil level. This much fuel will thin the oil and possibly not lubricate as intended. I hope this answers upu question. But feel free to ask more. I'll do my best to answer them 😃👍🏻
There maybe a screw in filter like honda and chinse copys filtee screws in from u der neath get torch look down in tank cap off if one there u will see bit of pai tank has to come off take notuce of way fuel line runs diection it goes if not u may squash fuel line cut fuel supply machine wont go lol i d iud it had to take tsnk back off rerout fuel line all good then
Yes, you are right. it was an internal filter (inside the tank) It was missing. So obviously wasn't there from factors. I done a follow up video showing this 😃👍🏻
😂😂😂 its always the 1/2"-10mm that Always missing.
10 and 12 for me 🤣👍🏻
U aussie or from nz?
South Aussie mate 😃👍🏻
Your snowblower video helped me save my $850.00 usd snowblower. Thanks a lot bru, 🍻
Had an engine come in for service and the entire crankcase was filled with gasoline. Yikes.
G’day Preston 😃. I’d believe it 😃🤦🏻♂️👍🏻
@@rustyinspirations appreciate your video! Subbed for sure!
Cheers Preston😃. And I appreciate your sub 😃👍🏻👍🏻
Yeah I’ve done all of this even tried the magic oil down the spark plug hole. When I put the spark plug back in it locks. I’ve even taken off the carb and cleared the fluid. Only 1 month old engine. The gas did flow to the oil and got into my filter, I removed filter and changed oil still locking up when I put the spark plug back in. When the spark plug is out I can pull it though. I’m very confused on what to do next.
Gday mate, the only two things I can think of is the spark plug being go long and fowling the piston. Or it's not completely dryed out and is still hydro locking? Sory I can't be of more help 😔
@@rustyinspirations does it have to be completely dried out 100% because I see people poor magic oil down the spark plug hole and they can pull and start the engine. Also the spark plug being too long? What could this mean, it’s all OEM off the engine. Thanks in advance.
If the plug is genuine, This wont be an issue. You don't want any fluid in the top of the cylinder, only vapour. What is the magic oil? Fuel?
@@rustyinspirations the magic oil is oil technically. Something people use when they get stuck because the gears aren’t lubed or something like that. I guess when you poor it down the spark plug hole it’ll eventually loosen up the crankshaft. There’s videos on TH-cam everywhere on it. So no fluid at all on the top of cylinder? So is it possible because it’s slightly wet that I can’t pull when I put spark plug in?
Got ya😃, are they putting oil down the plug hole because the engine is seized? I have done this many times in the past also. However your engine doesn't sound to be seized as such. The fact that it turns over while the plug is out confirms this. In wondering if the little bit of oil you are putting down the plug hole is just enough to hyrolock the engine? Sorry if im not a lot of help. It can be very different diagnosing something that I can't actually look at 😂
