    I have a Honda HRB216HXA.

    And so it appears that ethanol has claimed my fuel system; AGAIN. Last year I had the same issue and as I didn't want to dick with it, took it to small engine repair shop (aka Idiots). They claimed that the carb can't be completely disassembled for proper cleaning so they would replace it. That worked for a while but here we are again.

    Questions:

    1. Does anyone know if it can actually be cleaned out?

    2. A new carb is $15-20; should I even try to clean the little bastard?

    Thanks.

    Next we will tackle my big Echo backpack blower, weed eater and Honda pressure washer.

    Its a cheap lesson, its already not working,cant get any worse, pull it apart and see. The ethanol attacks any rubber bits and diaphraghms. good luck emti

    I went into it halfheartedly two years ago with that very thought in mind and was unable to rectify the problem. Even if it can't be fully stripped, there has to be a miracle carb soak compound out there somewhere.

    I found that Marine Clean from Por15 worked very well for carburetors.

    http://www.por15.com/MARINE-CLEAN/productinfo/MCG/

    Unfortunately it is a one-time use product.

    I really miss the old Hydro-Seal; it would turn your skin colors and the smell never went away but boy would that stuff clean a carb, and it would last for years.

    I've not had good luck with Pine-Sol.

    You have to find the idle jet and mechanically clean it out. Carb cleaner won't touch it. I've had good luck using a bristle from a fine brass wire brush.

    Basically, you have a new carburetor with clogged jets.

    And that may be the "part" you can't disassemble...

    There are a couple of videos on YouTube on Honda mower carb cleaning. Check it out and see if they apply to your model.

    Personally, for $15-$20 and not much hassle I would just replace the carburetor. It's not hard to spend that much on parts for other lawnmower carbs. Get a separate gas container only for lawnmower gas, buy some Sta-Bil gas stabilizer - follow the directions and use it - and keep only stabilized gas in the lawnmower and the gas can. If you really like disassembling the carburetor for no good reason (and I am guilty of that), keep the current clogged one to tinker with. YMMV.

    As long as you can poke a wire through the jet, that's all that's needed. I brought a little 600 watt Honda generator back to life this way. Once the carburetor's off, it's only another ten minutes to get it apart. The jet'll be brass, and I'm sure it'll be removable.

    Depends on how much you value your time. The shop where I bought my mower won't even try cleaning those carbs. They would have more money tied up in the labor for cleaning than a new cab costs.

    I shut the fuel valve on my mower off, and then let the mower run till it dies, when done mowing, every time I use it. This is my third season with thy mower and haven't had carb/fuel issues yet.

    Just FYI, but I have a mower with the same engine and it has seen nothing but E10 for the last five years or so. No problems. I do make sure I start the mower at least every month or so and keep reasonably fresh gas in it.

    I've cleaned a lot of carburetors over the years, and there's nothing except manual cleaning that will take care of a varnished idle jet. Not even the old type carburetor cleaner I still have and use. You have to poke the crap out with a wire.

    I have used one strand of a copper wire once or twice, normally that is on carbs that have sit for years. Some times it takes two dippings and a can of aerosol carb cleaner to get it done.

    Sometimes it's less trouble to just put new idle jets in, especially in Mikuni VMs because of the jet design.

    Based on my recent experience with a Honda generator, I'm a believer the Techron works better than Seafoam if you want to attempt to clean jets by running the thing.
