I have had an HRX217HMA for some time now & it is old (2005) but runs great. Recently picked up an HRX217K5HYAA which I believe is from 2017 or 2018. Both have the Roto-Stop clutch. While working on them, I was surprised to see that the older HMA has an fairly lightweight aluminum flywheel/fan...

Agree with Bert; check the valve lash. Here is a video but there are many others on YouTube.

Yes, that's a good thought. But I checked that, too. Torqued to spec, couldn't budge them any tighter. It's a mystery.

Just recently, the GCV160 on my mower started making clanking sounds, like 5 or 6 "clanks", when it powers down. When it is running at around 3100 RPM, it sounds fine. Took shroud off and spun the engine with a drill .. sounded fine, no clanking. So, when doing that, nothing is interfering with...

Have an older pressure washer with a Briggs Quantum. Since it is a 2001 model, the label still rates it in HP; ie, 6.0 in this case. There are calculators online that purport to convert torque to HP & vice versa. I have used them for that conversion in the past & come up with torque to HP on a...

Yes, I did this 2 years ago so I am on my 3rd mowing season. Acquired an good deck, good transmission (important!) HRX that threw a rod & busted the top end but everything else in the engine looked fine even, surprisingly, the crank. The 190 was off a unneeded PW that I had lying around. So, in...

Looks like you have the right part. But here is another option that worked better for me than the thermal wax on an HRX217. Might not work for your model though. https://www.lawnmowerforum.com/threads/convert-hrx217-autochoke-to-manual.65184/

I had that problem once. I learned that the entire mower (or engine if it is off the mower) must be lifted & tilted backwards at such an angle such that no residual oil can gravity seep down to the valve cover mating surface while the gasket maker is curing. Oil compromises the sealing...

Thanks.That's it alright.The engine turns at full rpm even though the blade has stopped turning. Similar to a pressure washer where the pump exerts nowhere near the rotational force of a lawn mower blade.

Have a Blade Brake Toro Personal Pace with a piston & cylinder scored Briggs 6.75 Quantum. My thought is to replace that engine with an older rebuilt 6.75 off a Troybilt with a rotted deck. In order to retain the blade brake feature, I have swapped the crankshaft from the Troy to the Toro...

Thanks. I usually empty the tank before tilting the mower for jobs that are going to take more than a few minutes. My experience, when I have mistakenly tilted muffler up, is with oil, not gas. That is, soaked air filter and lots of smoke when I get it running. This has happened on not only...

The title says it.; I realize this is a no-no. But sometimes it would be useful to tilt a mower on either side depending on what one is trying to fix. From what I have read, the problem is that oil flows from the breather hose into the airbox and even into the combustion chamber if tilted...

Friend brought me a 2020 Craftsman pressure washer with a Briggs Horizontal OHV 950 series engine. Extremely hard to pull over but not seized. Checked & double checked the usual suspects, keyway, valve clearances, recoil etc. Seem fine.Even removed the crankcase bottom to see if the timing was...

Are you seeking # 5 below? If so, here is where I found it & it is available. Inexplicably, it lists 2 widely different prices based on serial #'s. Guess you'd have to call to sort that out. https://www.boats.net/catalog/honda/lawn-mowers/hrr216k9-vlaa-vin-mzcg-8670001/battery-main-harness

You are right; that OEM charger is really pricey. Here's a couple of ideas: I have an older HRX217. I got it used for free but with no charger. I was able to look online at the specs on an OEM charger. Then I searched for identical specs in a box I kept of old telephone chargers. I found one...

Recently bought a replacement carb for my 6.75 Quantum on a Toro. It has the auto choke feature which is working as it should. But I noticed that it takes more pulls to get the engine started. Then I noticed that the choke plate is, for lack of a better term, partial (on left). Other Quantum...

I have 3 HRX217's; they all do the following. Even with the clip director set on full mulch, some clippings sneak into the chute. With no bag, some of the chute grass simply exits out to the mowed area and I haven't noticed any clumping. However, when I come up to my walkway, I see an good bit...

my bad. Here it is: https://www.lawnmowerforum.com/threads/convert-hrx217-autochoke-to-manual.65184/

Oops. forgot the link. https://www.lawnmowerforum.com/threads/gcv160-autochoke-keeps-failing.68886/

Here's what I did with a ornery thermowax issue. My mower is an HRX217 so I don't know if my solution will work for you. I was unable to locate your model but I did find an HRR216K8 (no "8" after the 216) and the parts on that model are the same or very similar to my mower. Essentially, my mod...

Got a used HRX217HMA a few years ago & got it working great. However, the battery was dead but It is a one pull starter so I didn't bother replacing it for over $100. Lately though, just because I think it would be a fun experiment, I began thinking about a replacement mod. I found the 12V...

Hey Mark, the battery in the video is different from the one you linked (the box is also different & maybe the harness). Don't know which one the OP owns. My older HRX217HMA uses the one Dony installs & is as much as $160 at some sites. The one you link is for certain K6 models which are newer...

Yeah, I've wondered about those "partial" looking butterfly's too. But in most cases, they seem to do the job even though they don't choke off the intake completely. I bet BertsMobile1 knows why Honda chose this bit of engineering. Anyway, I don't see where changing to a larger butterfly can...

First, your mower ought to be under warranty so your best bet may be to take it in. But the link below is what worked for me on an out of warranty HRX217 and I send it along because you have some experience with, and liked, a manual choke...

Never heard of a clogged fuel line. Unlikely since there is a screen in the tank that would prevent any but microscopic debris to pass through. Even if some debris did slip through, it might clog the carb jets but then the engine probably wouldn't even start & run. Again, check for spark if you...

Agree with Bert. But you could check for spark just to satisfy your curiosity. Dozens of YouTube videos on that procedure. Although fairly rare, I have seen coils that were either dead, intermittent (fine when engine is cold; failed when hot), or too weak to push a spark down to the plug electrode.

Back in the day (80's or so), Craftsman sometimes sold push mowers with Tecumseh engines on which the engine faced towards the operator, like below. Anyone know why this was done? By doing so, the spark plug is inaccessible with a socket for one thing. I believe that the blade would still spin...

Just thought I'd update since I started this thread almost 2 years ago. I have used a gasket vs. silicon on three GCV190's or 160's since then and none are leaking. The valve covers on them were in pretty good shape (not badly bent) so that's probably a big reason that it has worked for me.

Here is how I converted autochoke to manual rather easily. https://www.lawnmowerforum.com/threads/convert-hrx217-autochoke-to-manual.65184/

Thanks.The diagram you sent does not have the middle large barrel-headed screw or whatever it is (red dots). I'm trying to see if any one knows why that piece is there and, moreover, if it is actually a LO adjustment on the rightmost carb (K78 aftermarket) because that middle piece has a slot...

C1U-K42 or C1U-K78. I have seen either of these on this style blower ... the older gray Echo's.

Have an older blower, PB2100. May need a new carb. Searching online I see 3 choices. It appears that Zama OEM has a Hi & Lo adjustment screw but two aftermarket units may not have the Lo screw. The one on the right has a slot for a screwdriver but the middle one does not. That middle...

Got my first (used) mower with the autochoke, a "feature" that many folks dislike. I, too, had problems with it's operation even though the thermowax part seemed to be working properly. I decided to see if I could simply convert it to manual since I have a bunch of Honda carb parts that I saved...

Many Honda owners with Roto Stop, HRX217 notably, complain about the blade clutch not staying engaged while mowing. I have not had this issue with 2 previous 217's but recently acquired another 217 where the slightest release of the blade clutch bail (#12) (maybe an inch or two) caused the...

Yup, you got the # right. Try this Honda "Contact Us" link. https://crrs.secure.force.com/service/pew2c I recall that I used this link several years ago to find out the age of a used mower I acquired. Someone got right back to me.

Double check that model #. This site is about as extensive as I have seen & there is no HRX2172HXA listed. Honda #'s are mindbogglingly confusing. https://www.boats.net/catalog/honda/lawn-mower

Thanks for the reply. Trying to learn as I fix things. The OEM carb on this mower is clean; all jets open. The engine doesn't surge at any setting across the range of the throttle positions. So, I'm curious, why would a new carb cure the rpm drop issue when the Roto Stop is engaged?

Picked up a used HRX217HYA. Was over-revving. I adjusted the gov arm per Honda's instruction; ie, the shaft adjustment. Still over-revving so I bent the gov arm slightly to reduce tension on the spring. This put the unloaded rpm at a desirable 3200 at full throttle. However, when I engage the...

This may help. Click on the FAQ "How do I adjust the Blade Control cable?" https://powerequipment.honda.com/lawn-mowers/maintenance-and-support

It sure does help. thank you. Under a mag. glass there isn't a notch on either ring; the only real difference is that thin circumference of copper-coloring visible in the picture I posted previously. I got this engine in a trade & the original owner told me he hasn't performed a lot of...

I decided to use the ring with the copper-colored rim/edge as the 2nd ring. Honda for some reason differentiated it from the other ring and typically Honda colors the 2nd ring black vs chrome for the top ring for identification purposes. So, I reasoned that the copper ring is another way of...

With a magnifying glass, I examined the ends as you recommended. Did not detect a champhur. However, on closer inspection, I did see that one ring (bottom ring below) has a thin copper colored coating around it's circumference. That ring is also ever so slightly narrower (less wide) than the other.

Opened up a GCV190 that was smoking badly. Surprisingly, the insides looked good, cylinder, piston, crankshaft, etc. However, there was excessive carbon build-up on the exhaust valve such that it wouldn't close all the way. Thinking that this may have been the cause of the smoking, I replaced it...

Yeah, I'm thinking that the arch is there to make it easier to get the 2nd clip installed. The 1st clip is easier to install because you can hold the piston in your hand while twisting the clip into its groove. But the 2nd clip must be installed after the rod is attached to the pin, thus it is...

The retaining clips on the kit I got are identical; both have tangs. Which side gets the arch, the left clutch/shaft side (red dot) or right recoil side (yellow dot) or does it matter?

Am rebuilding a 128LD. Received the OEM kit from seller and noticed that the piston has different openings where the piston pin affixes Notice the arch on one side versus no arch on the other. The scored piston that I am replacing has no such arch. Is this critical when inserting the piston into...

Yeah, I agree that you are likely ok. Honda ... well ... does things different. The capacity of the engine is 18-20 oz. but when one changes the oil, he is only supposed to add about 12. The difference is residual that somehow doesn't come out when the engine is tipped over for draining. Go...

Anyone know what the NOT is for a GCV160 or GCV190? All the manuals I have found simply refer to NOT but none give an actual temp in degrees. I did find a forum where a Honda motorbike was reported at a max of about 210 degrees.

Glad it got solved. If it comes back, I kinda suspect the coil. Sometimes the heat from the engine exposes weakness in the coil which could explain why it runs for awhile & then dies. I mean, it must be getting fuel because it starts & runs for at least 2 minutes. Aftermarket coils on Amazon are...
