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...

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...

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...

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 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...

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...

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...

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...

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...

Hi. My first post in this forum! I ran my Honda HRX217HZA with the GC190 engine dry of oil stupidly about a month ago. It seized up and I thought I was done until I started googling it. Apparently a lot of times the piston can be freed with some penetrating oil and a wrench. I removed the...
