Thanks for that. In my case, the mower didn't have any oil in it yet. I probably gave it several days to dry. I'm definitely going to get a closer look at that little o-ring.

I assume you are talking about part number 14 in the diagram linked here: https://www.southmspowersports.com/Parts/Parts-Fiche/honda-power-equipment/lawn-mower/all/hrr216k8-vkaa/camshaft-pulley/e5ef451c-eb92-4670-b392-181403de135e If so, did you see leakage from where that cam shaft or pin...

Almost two years ago my engine seized due to lack of oil. I had noticed in retrospect that there was oil on the front of the deck underneath the general area of the valve cover. After much education here I was able to rebuild the mower and now it runs great. However, oil is leaking AGAIN from...

So I doublechecked the position of the governor arm and the pin to make sure the governor was putting up enough fight. I loosened the nut and make sure it was adjusted right. It actually fired up with a little too low RPM! That was the issue. I bent the governor arm a little and that put the...

I see what you are saying. I'll have to try that when I get home. The question is whether I can set the mower to idle speed and then lower the speed more by pushing on the governor arm. I think I can but let me try.

By "static governor" do you mean to adjusting the governor screw and making sure the arm and governor pin are fully clockwise?

I'm not sure I understand. You mean it won't work if I adjust the screw while it is running?

Yes, I have a tach, which why is I know it is running fast. Never heard of the tach app. Sounds interesting. I'll give the idle screw a try. I was hoping that is what it was. The other adjustment is to bend the governor arm, but even with no tension in the spring and the throttle on low it...

I can't find any info on the exact carb on my HRX217K4HZA. Photo below. I rebuilt the engine and my idle is a bit high. I identified the auto choke thermowax as one problem (thank you, Honda forum!) and confirmed today that the new one is working. I'm looking next to whether this carb is...

Somehow I never knew that Honda section existed! Thanks for recommending it. Lot's of good info there.

I have found with mine that some clippings leak into the chute but not always. It might be a matter of the clip director being dirty with dried grass and preventing a good closure. What I do is when I am near done with mowing I pull the clippings out of the chute and onto the grass. If there...

I rebuilt my Honda HRX217K4HZA mower and have other threads on that topic. The mower now cuts grass just fine but I'm having trouble adjusting the engine speed. It runs fast on full throttle, like around 4000 rpm whereas it should be 3100. I use a tachometer while I mow to keep the rpm's...

I tried cleaning up the bearing but I think the black marks are possibly from carbonized oil rather than from the gasket. This thing was running near 6000 rpm for short periods while I still had the bad governor. It's hard to say but scrubbing made very little improvement. I am using a brand...

I think those bolts are 12. I have been tightening them repeatedly while checking clearance with plastigauge and they seem fine. The bolts for the sump cover are cheap.

I'm using a torque wrench. The better quality bolts (the ones with numbers on the head) like for the crank bearing are not snapping. It is the cheaper ones that fail but I bought extras when I got the new crankshaft. I did not use permatex on the cap. I'm inexperienced, not stupid!! :)

Yeah, that's what I did pretty much. The instructions say to let it cure for an hour finger tight and then torque down. Let sit 24 hours. The first time I did it I let it sit for about a week and then added oil. It does say not for use in contact with gasoline. I did have a flooded engine...

So you don't think the small scratches will be a problem? I think the black marks are from the gasket material mixing in with the oil for some reason. When I dumped the oil it was dark. I'm concerned that the same thing is going to happen when I put it back together -- that the gasket will...

Hi. I've been trying to repair my Honda mower with a GCV190 engine since late winter, time permitting. (I ran it dry on oil and snapped the connecting rod last year.) The recommendation on this forum was to clean the crankshaft journal with acid and give it a try. I put all new parts inside...

I'll give that a try, thanks.

Thanks for the replies so far. A quick background and then a guess: Ran mower dry on oil last year and cratered the connecting rod. Took it apart and the cylinder looked fine. The rod journal had melted onto the crank bearing so I cleaned it up with acid per recommendations here and it...

I just finished rebuilding my Honda HRX217K4HZAA mower (twice, actually). I'm having trouble with the pull start. I've been using the rope because the battery on the electric start is drained down right now. When I put the mower back together the pull start worked fine. Now I'm finding that...

Just to close out this thread -- I put a new governor in the engine and got it running again. The mower ran at the perfect RPM right off the bat! Lesson learned. If the governor weights are not moving freely all the time when you touch them then replace it! I do have another issue now but...

I got the engine apart to see what's going on with the governor and here is what I found. One of the weights was sticking and so it appears that the governor was not able to provide the force needed to push the arm. I did two short videos. The thing is that I saw this before I closed it up...

Well, in my case the snapped rod was caused by lack of oil. :mad: Thanks. Part 11 pushes against part 12 to govern the speed. If the throttle is lowered part 12 will be in a slightly different place since it is connected to the governor arm but that probably doesn't matter. It's a little...

LOL. Thanks for the encouragement. I don't mind redoing it. What I mind is if I redo it and then somebody says, "Oh, that's not the governor. It's just xyz problem with the carb. But, yes, I can tear this thing down in no time at all now! I'm going to take a photo of what I find in there...

So I just looked at that part 12 and there is no groove on it to get a pliers on. It is just a round pin so I can't confirm that it is in wrong. However, your comment about resistance is helpful. When I have the mower on full throttle and the speed spring is tight the governor arm is vertical...

Another comment on that drawing. Item 12 the governor arm shaft actually has to be turned up 90 degrees so that the flat end rests against item 11, the governor slider, right? I can't be 100% sure that I checked this but I can't imagine that I didn't. I might be able to confirm this because...

That's what i'm trying to confirm by process of elimination. I was worried about the governor because you can't see it to confirm that the gears mesh, but then you can't get the cover back on unless they do. I can't specifically recall where the paddle arm or pin was when I put everything back...

Yes, that is the correct drawing. There is a gear that meshes with the gear on the crankshaft. This spins two weights that raise and lower the pin that pushes on the governor "paddle" that is connected to the governor arm outside of the engine.

When I start my Honda mower it revs like crazy to about 6000 rpm (3100 recommended max setting). I don't let it do that for very long. Prior to this I had to take my engine apart to fix a connecting rod problem but I never made any adjustments to the governor. I also did not take the carb...

I had to tie off the governor arm with a tie wrap in order to get the mower to run at the proper rpm. I was able to mow the whole yard that way but obviously that isn't sustainable. I tried adjusting the governor by turning the pin counterclockwise. It would only turn a very small amount and...

Now that that's fixed, next problem. Please watch short video. Thanks.

Thanks, I think...:) As I said I never touched the governor. The governor arm is in the vertical position at max throttle as it was before I took it apart so I figure I'm ok there. I was just a little nervous about the governor gear meshing with the gear on the crankshaft simply because I...

Hi all! This is a mower that I ran out of oil last year and with the help of this forum I was able to disassemble the engine and rebuild everything. Of course, I had all winter and now the grass is starting to grow and the mower isn't right yet. Background: Replaced failed connecting rod and...

Actually I think I'm OK. I just took a look at a guy removing his engine from The same mower I have and I can tell good enough what hes doing. It doesn't look like anything needs to be greased.. Thank you for your help.

Mine looks pretty different but I'll give it another look tonight.

Hi. I'm trying to reassemble my HRX217K4HZAA mower and didn't take enough photos to see how everything goes together. I guess it's called the blade clutch but not sure. I'm talking about all the parts behind the blade that fasten to the crankshaft. Here is a parts diagram of what I'm talking...

Sorry guys false alarm. I found a very high quality close up video and I immediately knew my problem. I did not put a nice long bead of oil into the groove before putting the rings in. What was impossible without oil became very easy. Lesson learned. I appreciate everybody taking the time to...

HRX217K4HZAA I removed the rings from the old piston (oil rings) and they are difficult to get back in, too. There are some videos about this but none talk about what I'm seeing. I'm pretty sure I have the right parts. The 2 oil rings look identical in every way

I got a new piston and ring set for my lawn mower and I'm having a little trouble with the rings. There are 3 grooves in the piston and the bottom groove is for what I guess is called the oil ring. It consists of one solid ring plus 1 corrugated looking ring plus another solid ring like a...

I've been away from this lawn mower repair project for a few weeks but I did manage to get all the parts I need. I'm doing some final cleanup, lapping valves and so on before reassembling everything. I have a question about the oil seal. On this motor the seal is kind of a metal honeycomb...

Yes I understand but for some reason there's an extra A at the end of the model number when you go to look up parts.

Fantastic! Thank you very much. I see they throw an extra A on the end but I'm not going to quibble. I do have a follow up question if I may. Some of the parts are different depending on the engine serial number. Is the serial number that is shown next to the model number for the engine or...

So this is very annoying because something that should be very simple appears not to be. I cannot find my Honda mower model anywhere on parts supply stores. I know I'm not the 1st to have this problem. I have a model HRX2174HZA. I think the 4 might not be important but I can't find any...

Quick question: I was having a conversation today with a Toyota maintenance instructor about my little engine rebuild. We got onto the subject of how the rod bearing on the crankshaft is lubricated in this engine. As there are no holes or grooves in the journal I wasn't sure. I haven't...

So I'll add compound and one of those suction cup gizmo's to my shopping list.

So I removed the valves today and spend a few hours on youtube looking at the wrong way to clean the valves... everything from bench grinders to chemicals. One of the valves is black and I thought I'd give it a gentle cleaning with the red scotch brite and WD40. That seems to be pretty safe if...

I'm going to remove the valves today and start looking at cleaning things up. I noticed that the cylinder head is kind of black. Should that be scrubbed clean and if so how without damaging it?

Thanks. I've managed to get this far without spending much on tools I'm going to use once, but I think I need to invest in a torque wrench. That comes in handy from time to time. After I get the crankshaft in good shape I need to take stock of how to rebuild this thing. I need to do some...

I actually have the muriatic acid and I've been cleaning the journal which looks like it will be a good shape. However I'm still not sure if this crankshaft is going to be usable. For instance I scored the top of it with a pipe wrench while trying to get a nut off the bottom of the mower. Since...
