    Like the others, I enjoyed this video. I own the same model snow thrower. Mine is one and a half years old, and I can buy gasoline from an FS Station that has 100% gasoline (no ethanol), but the station is 40 miles away, so I did it once and no longer make the effort :-) Stabilizer seems to make my Hondas (generator, mower, and thrower) idle rougher. Less steady, so I stopped that, too. My best solution that has worked for me for the 18 months that I've owned the snow thrower: start it once a month and let it run for 15-20 minutes ( even have it in my phone reminders). I turn the throwing blades for a couple minutes (hold the handle), fully rotate the chute, pretty much exercise all cables and moving parts. Not only does it keep the gasoline flowing, but it reassures me that the thing still runs. LOL Thanks again, panofish, as I get a sense everyone, sooner or later, has that issue as you, just the same. Wayne in Chicago.

    There's an access port on the left side that allows you to drain the bowl for longterm storage. If you run the machine dry and then drain the bowl, you're far less likely to encounter these issues.

    I have the same Honda HS720 snowblower and also had the same issue - hard to start plus rough running in year 2. As it turned out, it was the old bad gas I used. Yes, I added stablizer in the fuel but it didn't help. Lessons learned: do not use any left over fuel as they don't cost much (I only buy 1 to 2 litres at a time). Run off all the fuel remain in the snowblower at the end of winter.

      All true, but if you want to take one step further. Only buy recreational gas (if you can find a gas station nearby that sells it). Significantly less corrosive and gumming properties for these small engine carbs.

    I also bought a Honda 720 this winter. The dealer emphasized that I should use the premium grade gasoline as all others contain ethanol in our area. The snowblower came with premium and always started on the first pull. When I refilled it with some older gas that I had (regular octane) it would take 5-8 pulls to start. I drained it and went to some new premium fuel and right away it went back to starting first pull. It's a great little snow blower, just likes the premium gas!

    • @thomasmarshall4472
      @thomasmarshall4472 7 лет назад +1

      I'm not sure what to make of that. Higher octane gas is not "better" gas, it just has a higher flashpoint. If anything, going to premium would require a higher compression (or hotter spark) to ignite. Is it possible that the regular gas you bought was somehow inferior? My honda single-stage requires "86 or higher".

    Hi guys - just bought my HS720AA - good end of season deal. I have always used Stabil in my small engine gas tanks (outboards(2and4stroke), 1989 Honda lawnmower, Deere garden tractor) when putting them into storage coupled with either running the carbs dry or draining them. I make sure that the treated gas makes a final journey thru the carbs before emptying the carbs. Have always used Shell regular ethanol fuel - no more than 10%, Plan to do the same with the 720; Honda has a convenient drain screw and tube on the carb - nice touch. On engines where the input fuel line is easy to get at, I will inject a final dose of pure Stabil directly into the carb to make its way to the bowl. Overkill - yes; but never had a problem.

    Brand new HS720 purchased at end of last season. I started it up and ran it but didn’t get another snow so I never used it. Stored for the summer. Just fired it up and it was hard starting!! It take 2-3 minutes of intermittent cranking on the electric starter. Yes I gave the starter a break after 10 seconds of cranking so don’t bust my balls 😂😂😂. It finally started but it runs with what I call a “fast hunting” so I pulled out the choke and it ran smooth. Pushes back the choke and right back to fast hunting. Any ideas or advice from this group of Honda Snowblower owners??? Thanks in advance.

      Definitely you need to clean your carb. Also, in the future, use recreation gas without ethanol (this greatly reduces the chance for gunking up). Super common. You description fits. No doubt that you need to clean the carb ... the jets inside it are partially blocked with gunk.

      @@Fresh-tw7ev I don't think there is a way to avoid removal of the shroud. However, your best shot is to empty the gas in the tank... get some rec gas and start the engine with that gas ... then get it running with that gas... it will likely break the gunk ... maybe overnight after a short run trying to get some of the new ethanol free gas into the carb and let is sit ... then keep running it off and on until it starts to run smooth.

    I suspect if you had a Honda shop manual it has a step by step sequence which makes it much easier to get the carb off. I have a Honda HS622 track I bought new back in 1996. It still runs and looks like new. That's 23 years old. Maintenance is the key to taking care of anything. I did have the dive wheel seals replaced last year as they had started weeping. It's Honda road again. ;-)

      Just checked.. they do sell the shop manual for my model. I may get it eventually. This problem hasn't recurred in a long while.

    I would like to recommend a healthy dose of Seafoam when purchasing the new gas and draining the blower every Spring. After I drain, I take the bowl off my Toro and spray carb cleaner up the main jet that you pulled out of yours. I've had great results doing it that way.

    • @flipnotrab
      @flipnotrab 5 лет назад

      You are 101% correct. All ya gotta do is drain the carb bowl, then run a good mix of SeaFoam & Stabilizer (or Techron) in it. Close the gas valve and let machine run itself out of gas. Drain the bowl and your good. I’ve shot a little carb cleaner up that drain bolt hole before too. Can’t hurt. Gas is sucks these days. I’ve switched all my “rare use” 2-strokes over to the expensive store premix stuff. It’s cheaper in time & money than repairs. Shelf life of 1.5 years on brand I get.

      @@panofish If you are adding Stabil to E-10 it will not do the trick. Been there done that and paid the service bills for carb cleaning. At best, you can expect 60 days of stability, adequate for occasional use during a single season but definitely not sufficient to avoid fuel problems between annual seasons. As for price, if you're a pro doing 10+ driveways every snowfall you're using enough fuel to circulate the stale gas, but if you're a homeowner IMHO its worth $5 more each snowfall to avoid service issues. I recommend you completely drain your stabilized E-10 at end of season and run the machine with a can of TruFuel before you put it away. Also a good idea to drain the carb bowl at season-end.
