Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Just changed the sparkplug on my HS928 today and it was not as easy as my Honda lawnmower.  The angle is somewhat skewed so regular craftsman sparkplug socket is not the best.  I had to use the Honda socket (thinner) that came with the blower to loosen and tighten the sparkplug.  When you are installing the new sparkplug - try to tread it with your hand first before using the socket so you do not strip it.  Just be careful so $2 job does not turn into a $400 mess. Did you guys have similar experiences on your Honda blowers?

I'm not sure how the Honda VIN code works but I would also assume that the higher the number, the newer the machine. I thought you may have deciphered Honda's code and were able to determine the exact day, month and year of manufacture from the alpha-numeric code assigned to each machine.

I wish.But I do not think the VIN is coded.Just from smaller number to bigger number/from older to newer.

For example on HS35 they made design chnages on the auger guard/scraper area.

Up to frame serial number 1048328 the first design was used, and from this number up the new design was used.

I changed the spark plug on Honda HS35.At first it did not stay running.After a while I realized I did not tighten it well.I did not want it to get stuck there if I overtightened.After tightening more it is good now.One thing I noticed, the tiny tip of the spark plug where it meets the spark plug wire needed to be screwed out because it does not fit the way it came in the box.

I wanted to change the spark plug on Honda HS621 but the wrench I got for HS35 was too short although it is the same size so I could not put the handle.Now do I have to buy that expensive wrench for this one too?It is 13-14 dollars.

Just a thought, wouldn't a 5/8" thin walled deep socket with an 6" extension work for both of your machines?

I even got a 5/8" 12 pt. spark plug socket. It is too small.
