Mine is hard to pull even without spark plug and I took the thing apart and when I disconnected a plug that leads to the electrical parts it was easy to pull so I plugged back in to see if it was the reason and it was cause when it's not plugged it it turns fine but when I plug that back in it's hard again. I'm assuming there's a clutch of some sort that engages when it starts but is malfunctioning. I'm assuming it's supposed to disengage when stopped and engage after the engine starts more
Mine is doing the same. I fully disassembled after checking the easy stuff. The decompression lobe on the cam is no longer functioning. Mine needs a cam. more
Could have been a compression problem which got worse because there was no ignition. That's why some chainsaws have a push button on the cylinder-head to relieve pressure in the cylinder, which makes it that much easier to start them. (otherwise with each pull the compression gets worse and therefore the pulling gets a lot more difficult) more

I have come across this problem on Multiquip generator/welder combo. After talking to a representative from the company and doing some electrical diagnosis, the problem was the transistor PTR. If I removed the generator section from the engine, the engine started right up. I put it back and it feels like someone is holding the output shaft, lots of resistance in pulling and could not start it. After the new part was put in, it started right up. The tech said it creates something along the lines of a "electromagnetic gate" the resistance in pulling starting is created from parts of the generator acting like a magnet. Hope this helps some of you. The part was very expensive by the way, I think it was either $400 or $600. here
So, even though it is rare, if this little tiny piece inside of your crankcase gets damaged you’re going to have one heck of a time starting your generator until it is fixed.
Hydrolock can also be caused by water being inside of your combustion chamber if you left your generator outdoors and water can enter in through the exhaust if it rains hard enough. That water can also lead to rust which can also seize up your piston but we’ll get to that later. here
Throwing out your shoulder in the middle of a power outage as you are trying to start your generator is definitely not in the dictionary as a definition of a good time.
Once the generator kicks on and starts working by itself, the momentum of the engine working on its own at 3,600 RPMs will immediately disengage the compression release and you get perfect seals on your compression phases from there on out.
Now that we have crossed off the top 3 easiest reasons, we’re going to proceed to look at your piston to see if it’s seized up for one reason or another. [links]
If hydrolock was not your problem, I would then check to see if it’s just the recoil starter cord itself. Sometimes the rope can get bound up on itself and jammed up inside. here
Thank you. I ended up with t extra screws, but everything worked out.
It’s inevitable… if you own a Honda EU2000i generator, sometime during your ownership you are going to have to replace the starter rope. We’ve heard from other owners that their starter rope frayed and had to eventually be replaced. And, so it happened to us. At first glance this will seem like a daunting task, and rest assured… it is. 😉 But the end result is achievable.

Thanks Mike. We’re glad the post was useful. Thanks for visiting our blog. more
Step 14: Remove Left Front Frame Screws – (2) P3 Screws – NOTE: Do Not Disconnect Longer Fuel Tube. Just lay frame aside once screws are removed. There is no photo of Right Front Frame (1) P3 Screw. So wing it yourself.
By the way we are in Western Australia. I broke the plastic base trying to undo the Phillips studs, but some wire and the drill gave an adequate fix. Used an old shoe lace as the replacement cord. All working well now. here
Blade Brake Clutch models feature a clutch device between the blade and engine. You can usually start the engine without holding any levers or controls in place. After the engine is started, you engage a blade control lever, usually a 2-step process. On Honda mowers, there's a yellow button that must be pressed in, then a lever moved into position. This engages the blade clutch and the blade starts to spin. Release the lever and the blade clutch stops the blades, but the engine continues to run. [links]
Flywheel Brake type mowers are the most common. The blade is bolted directly the the engine; if the engine is running, the blade is spinning. They require you to pull back on the blade control lever and hold it in position to start and run the mower. When you let go of the lever, the engine's ignition is stopped and a brake is applied to the engine flywheel to make it stop spinning < 3 seconds. You have to pull back on the lever every time you want to restart the mower. With the lever released and the flywheel brake engaged, it should be hard / impossible to pull the starter rope and make the engine turn. more
On the back edge of the mower deck, you should see a model name and serial number; if you'll share the serial number with me, I can look up service details for you; it's in the form of "MXXX-1234567" here
It's simple to forget to add oil to a four-cycle lawnmower engine, and when it is added, the piston has no lubrication and can seize. If the mower runs out of oil while it's operating, major repairs are the usual result, but if it happens when the engine is cold and you're trying to start it, adding more oil should free the piston. Check the oil dipstick. If it shows that the crankcase is empty, add the recommended oil for your mower. Put on leather work gloves, and gently push the mower blade until it turns, or push the blade from a safe distance by using a stick. After you can spin the blade freely, you should be able to pull the starter rope to start the engine. [links]
If you have a rotary lawnmower and it's been awhile since you looked underneath it, now is the time to clean old grass and debris from the blade and the underside of the housing. Small rocks can catch between the blade arbor and the housing, preventing the blade from turning; because the blade shaft is connected to the crankshaft, the starter won't turn either. After the mower's underside is clear, pull the starter rope while depressing the brake lever on the handle if a brake lever is present. If you forget to depress the brake lever while pulling the starter rope, the starter won't turn and the engine won't start. more
If the blades are clean and the engine has oil, it may be the recoil starter that is at fault. The starter includes a spring-loaded hub that spins the engine crankshaft and the lawnmower blade when you pull the starter rope. The spring can bind or even break, and it's possible for the rope to cross over itself when it rewinds and get stuck. Removing the starter from the engine housing is a straightforward task in most push mowers, although in some, other engine components, such as the gas tank, may have to be disassembled at the same time. here
When a push lawnmower's pull string, or starter rope, locks up, it could mean the engine has a problem, but that usually isn't the case when oil is added to the engine regularly. On a rotary mower, the starting mechanism is connected to the cutting blade, and a buildup of debris on the blade can make starting the mower difficult. The problem also could be with the recoil starter. Unless the engine has seized, you should be mowing after a few minutes. here
After you've loosened the screws holding the starter to the engine housing, it just comes off. In order to access the spring and starter rope, remove the rope from the hub, and remove the hub from the recoil housing. This should be done with care because the spring still may be under tension. After replacing the spring - if that task is necessary - wind the hub until the hole in the center lines up with the hole in the housing. Holding it steady with a screwdriver, feed the rope through both holes, tie a knot and allow the hub to unwind slowly to wind the rope. The starter is then ready to screw back to the engine housing.
