Honda HS621 restoration
Original Message   Oct 27, 2013 8:57 pm
Well here is my most recent find.  Actually I bought it at an auction back in August.
But didn't get around to restoring it until earlier this month.
It was pretty rough but started on the second pull. So figured it
was worth the 40.00 I paid for it.


   

The upper handle was pretty messed up.  So I replaced it with one that I kept around from and old Toro CCR2000.
It bolted right up and was also a little longer than the stock Honda handle.  Which is nice.





Stripped and repainted the muffler cover.  As well as the lower handles.


 

The blower housing sides needed quite a bit of straighting.  Also welded on a small piece of steel onto the bottom of the left  side
where it had been worn off.  Not adding the piece would have allowed snow and water to get inside what is the belt and pulley
compartment.  That would not be good.  Installed a new set of paddles and a new scraper that I bought on ebay for $53.00

 


Cleaned up everything inside.  Have to say that these blower are really well built.  The steel used for the bucket and the
undercarriage is heavy gauge.  Actually the undercarriage is plate steel.  The bracket between the engine and the bucket
is like something you would find in a automobile.

 

Sandblasted the bucket and sealed some of the joints with auto Spot putty.  Gave it two coats of Rustoleum Red oxide primer.
Then two top coats of Krylon Tough Rust semi gloss.  I did end up giving the center interior section of the housing another
coat of black Rustoleum Hammer finish.  That gave it a smoother, slicker finish and that paint if extremely durable.
That is also what I painted the auger with.

 



 

Didn't do much else other than check the carb bowl for dirt or signs of water. 
Replaced the plug, oil was good and clean.  Belt was good.  So it's ready to go.

In case some of you noticed there is a modification that I made.  I designed a chute rotator system for it.
Which I will show in another thread.

I'm guessing it's around that age, maybe a bit older.  There's a forum member here that works for Honda that may be able to find out the exact month and year of manufacture from the serial number of your HS621.  In any case, your machine looks like it only actually moved snow for one season and did a Rip Van Winkle all these years until now.  Hopefully the fuel lines and all rubber components are not dried out and are brittle.

Went over the whole machine and its like new. He used mobil 1 and drained the carb after every use, and kept it in a heated garage. Its truly a perfect machine :)

I can only access digital records back so far, (about 1999-2000) and mfg. dates / serial numbers older than that are probably on some little white metric-sized index cards in the basement of the factory in Japan. The HS621 was introduced to the USA market about 1992, and discontinued in 1998.

Unlike mowers, which get used every year, snowblowers can last for decades, as they don't get used every year in many locations. Still, it is awesome to see equipment 25-30 years old still in use.

Actually using it for 4 years I can clearly say that the initial $50 cost has been absorbed :)

I hear what you're saying.
But that doesn't change the math.

No, I wouldn't say that.  Those things are considered maintenance and operating costs.
That's different.

I know it's not a big deal. I only made the comment to clarify things for
others that haven't read all the posts.

Even if you were off by $100, that is still an awesome machine you got at those prices.  :)  That's why I'm not nick picking.
