thanks for reporting back the conclusion.

So looking over this thread. It does not make sense. The statement is that the intake manifold is missing off the carb along with the air box. The carb bolts to the intake manifold so I have no idea how the carb could be there and the intake manifold not be there. Maybe the OP can post some...

I have a policy when fixing things. If people have money, they pay for the work full shop rate. It they break it, they fix it. If they can't afford a repair, I might cut someone a break if I sense they take care of things. But if they are hard on things and are broke, that sounds like a...

"grinding" doesn't help a lot. Grinding teeth vs teeth? Grinding against the frame? No idea what from, just making noise? Does the wheel skip when this happens? I don't know if this might help but when we used to build racing engines we would sometimes use modeling clay to determine...

the majority of the members here are here to help others, but trying to turn a wrench or use a meter over the Internet is a bit a of challenge. My apologies - thought you were flaming me for trying to help you find a solution to your issue.

if it stopped suddenly when you snarled the rope, it could have broken the flywheel key. If so you will need some mechanical tools and knowledge to fix it. If you flooded it then pulling the spark plugs and cranking it for 10 -15 seconds, then puttin the plugs back in and trying again may fix...

must have fixed it. Newbie who has been gone for a week now.

was the tune up to fix the problem or did it appear after the tune up?

did you clean the fuel tank and any screens in the fuel outlet? Might be a little water in the fuel that is moving around on an incline.

cool. A 1960's Heart Attack Special.

Was the problem the reason you serviced it or, was it running fine then you serviced it and the problems started? This is an important question. You posted Sunday, it is now Thursday night. You are a newbie, and if you don't comment about the status, people will abandon this thread because...

I pulled this wiring diagram below off a Google search. I do not know if it is yours or not but it was in the owner's manual so it would be easy for you to confirm it. The wiring shows the grounding kill wires coming from each coil in a Y to a single wire that goes back thru a connector to the...

https://cdn.powerequipment.honda.com/pe/pdf/manuals/00x31vh7n030.pdf please look at the maintenance schedule under 150 hours or every two years

I recall that there have been other threads where a bad diode caused this.

check the belt brake pad. It is a known issue on some mowers. When the pad is too worn the geometry changes in a way that the belt is too loose and jumps off. Have seen several videos on it, and I was quite surprised how much the geometry changes with worn pads on some configurations. The belt...

What was the air gap you set the coil to?

Specific questions: Can you tell us what led you to check the flywheel key? Was there a blade strike of some kind? Were the plugs put in after the last run or before? What brand and where did you get them? Has the mower completely dried out or is it still in a damp area? Do you have an...

looking at your photo it feels like we are being trolled. That cylinder appears to be freshly honed. There appears to be no wear in it since the honing. It looks like a recent DIY hone. The angles are too shallow and the stone spun round and round at the top like it was done by hand and not a...

even though you say you have spark, not so sure. Could be a bad spark plug too. Have you made any changes since the last time it ran?

only in chatter. Most people are unaware that the solution to getting rid of hazardous waste in California often involves contractors who take it across the border to Mexico, Utah, or Arizona. https://calmatters.org/environment/2023/01/california-toxic-waste-dumped-arizona-utah/

trolling today are you?

yep. wasn't always this way.

we live in state that outlawed sale of new ones. Would not be interested in chasing down a good used unit, restoring a neglected one, or going out of state for one then smuggling it back in. Some counties have even banned use of them at all. The yard takes very little trimming, just enough to...

I watched a Project Farm on trimmer line. Then read reviews on Amazon. Then looked for factory spools or bulk line. Out of stock online. Then no one local has the factory spools. Dumb. Guess I will soak the Oregon line in a bucket of water like they suggest, respool it and see if it helps. The...

I posted a thread that led to three major salvage yards, and a path to find your parts. Because the solution required reading thru to the sites, or making calls, you *****ed at me. No problem, the sites are deleted. Find them own your own.

the only decarbonize fluid that ever worked was the GM Upper cylinder stuff that was discontinued. I did a test many years ago of five or six different well known decarbonizing cleaners and the GM one was the only one that actually 100% softened and washed away the carbon. But smoky and stinky...

Thank you but looking for a solution to make this one work. There are plenty of other solutions including a Toro unit that has the insdustry common metal head, and uses the same 60V batteries we have now. Not looking to start over with new batteries and chargers etc., or spend several hundred...

First, I would not do this model again. That said. The first one lasted 15 minutes. The string wrapped around an iron stake and pulled the head apart. Parts are not available to fix the head, Lowe's / Toro warranteed it. This one is still running five years later but it is just as bad feeding...

what torque did you use, and have you checked your torque wrench lately to see if it is accurate? Overtightening or undertightening can cause that. If it was undertightened it could have backed out. If it was over tightened it could have stripped or broken. Honda manuals online for the HR214...

^^^^ what MParr wrote in the last two posts is the answer I would have also given. On things like this, I try to stay away from Amazon and Ebay these days due to the high number of cheap counterfeits out there. Sometimes Summit Racing Supplies will have certain brands of oils and fluids that...

the HR216 was produced for about 15 - 20 years. Probably going to need a full model number and serial number to answer the question. Thank you for deleting the duplicates. Looking a a picture of a sample of one of the several different brake pads used, it would take special adhesives to...

on a mower engine I would resuse the bolts unless they are damaged or heavily rusted/corroded. Alumium is considered a passive metal. A primer is needed for Loctite to properly cure on an aluminum to aluminum surface, however, you are using steel bolts and that is an active metal. Personally...

both area and close up photos would help a lot here.

as sheenist said, there are bone yards in the midwest that searches for mower salvage yard, used mower parts, mower bone yard etc. Then get on the phone and start calling around. this is an example of some of the sources. There are many more https://fultonmowersalvage.com/

there's a lot of them lately, signal left, get in left lane, go right across 3 lanes cutting everyone off.

read this thread. https://www.mytractorforum.com/threads/honda-76221-750-000-ht3813-deck-spindle-pulley.1379461/

^^^^What others have written above^^^^ The company is Dana-Spicer. They typically label their equipment Dana. I think Allison bought them. Also sold as Foote corporation products, or sometimes private labeled for companies like Craftsman, John-Deere etc., Husqvarna. With the age of the unit...

make sure that the RPM is down and not just the speed at which things are happening. Slipping belts and transmissions will slow things down even though an engine is performing flawlessly.

so which cylinder is not performing well? Make model serial number. How many hours on the engine. Is the RPM down or just the speed?

labor is cheap these days. Mark the rocks, and hire someone to remove them. As for roots, that is a species and soil compaction issue. Often digging the root up can damage the tree. So have to make a different kind of decision on that. Maybe make some planter beds around the root areas that are...

we have the same issue with classic VWs. The main culprit is that the condensers don't hold their value and it causes the points to arc too much when they open and close. That causes high resistance. I have found that the best solution for new points and condensers is Echlin at NAPA. If one can...

thank you for sharing. Someone will benefit from it when theirs dies the same way.

I would look at the ignition switch next. Also if it has a low oil switch and sensor that could cause it. Three things are needed for a gasoline engine to run. Spark, air/fuel, compression. One is missing. Help yourself solve the cause by first figuring which of the three are missing when it...

Most likely the starter is spinning but not moving out the gear to engage. There are many different types of starters so the rest is up to you. Some the solenoid controls it, some are forced out by the spinning action. Worn gear, broken teeth on the flywheel, broken parts in the "bendix," some...

Slightly loosen the fuel cap and see if that helps. It may be pulling a vacuum. Also tight valves can do that. a bad plug can too, and with all the counterfeits coming from online retailers, and off brands, that is a possiblity too.

many are not aware that spark distance gets less and less as compression goes up. Weak spark on a plug outside the cylinder may be no spark with compression. My favorite tool for checking spark is an inductive timing light. One needs 12v for many of them. There are rechargeable battery powered...

I did it for a living in a machine shop many years ago, learning that trade from a master who built engines and racing cars for the Unser family and others. Also street cars, classic cars, fleet cars, motorcyles etc.. Generally the bore is sized to the individual piston. It is not cost effective...

If this is the DuraForce engine, below is from LawnBoys web page FAQ at Archive.org about 2000. If you still have the manual it should be in there. If not, Ebay has them for sale as low as $7. Q: What about oil needs? How do the needs of this engine compare to those of a four-cycle engine? A...

replacing the diaphragm is what probably fixed it. Those carbs don't last all that long if fuel is left in them when shut off. I finally got years of service without problems by completely draining the tank after every use, and running the engine until it died. That was true for multiple...

the next thing would be to look for a vacuum leak. There are engines that have, for example plastic intake manifolds, that can crack. The symptoms you have listed are either lack of fuel or too much air. Bad fuel acts the same as lack of fuel. See if the engine runs better with the choke...
