Hello all! I’m the owner of an old HRU216K2 in Australia. I’ve been putting a lot of effort in to getting it back to running condition (it was very cheap but very rough when I bought it; a bit of a basket case).
So far I’ve been fixing up wear parts and replacing damaged or missing bits with genuine Honda parts (except for the wheels), like rebuilding the transmission, and now it’s running well.
I’ve had some challenges though that I’m keen to get some advice on.
1. I have a fuel leak at the carb. It wasn’t leaking before, but I stripped it, ran it through my ultrasonic cleaner and put it back on the mower and now it’s dripping fuel on the deck. Tried to knock the carb as I suspected it was something caught in the bowl but keen to hear if anyone else has some ideas on what to check? I did leave the fuel on so maybe that was my problem but it didn’t leak before when I did that.
2. I’ve been having problems with the motor bogging. It also had a misfire which a new plug cured and I also struggled with setting up the throttle control section (which was quite bent when I bought it). I also suspect I set the govenor wrong as I had no idea what I was doing. It was struggling with basic mows On standard height and as I’m trying to manage thatch it wouldn’t cope at all. Stalling a lot as I tried to take a cut with only 1 step down on the deck.
I set the govenor off a video that was linked off this site (to the Honda website). Push govenor arm right, inner rod to far right. Tighten.
That and I found a service manual link off this site too which gave some info on how to set control linkage. Throttle to fast, undo cable holder on control linkage and set the position so that it just engages the choke. Tighten.
All seems well with the motor now. The revs are not high, actually very reasonable and I need to do another 1 notch down pass to see if there’s an improvement, but if anyone spots any errors in my thinking, please let me know.
If it still has a bogging issue I’m out of ideas.
