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 wonder how much of my Honda blower is really made in Japan.

Give Honda a call.  Let us know what you find out.

Did you know that the Honda Accord has 75%+   US content and so big and bloated, it's only for the US market?

I got this wrench and the accompanying bar from there.Looked it up under HS35. (G150) So it fits this snow blower.But will it fit HS621 (GX160) also?

I ordered it, I have not received it yet. I wonder if they are going to be from Japan or China.

40 dollar price must be for a set like this:

How old is your snowblower?  A sparkplug should last 6-8 years in a modern lean burning fourstroke snowblower. That is like changing your cars sparkplugs if you drove down to Florida.

I do not know why MN_Runner wants to change his snow blower's plug but in my case:

HS35 is probably between 20-30 years old.One of the first 6000 of HS35s made according to VIN.I bought it used very recently.I have no way of knowing if the previous owner replaced it or not.

HS621 is also one of the first made HS621s if we are to believe VIN.This one looks better taken care of than the other.It is 2 dollars a plug (NGK), why not? If it is going to make more efficient...

I changed it for fun and just checking my mechanical skills.  I change it every year since the cost is only $2 at Fleet Farm.

Well,yesterday  I received the spark plug wrench and handle I ordered. They both were made in Japan. I am happy.

How did you determine the age by the VIN? Is there a sequential code or are you just using the numeric sequence of the numbers after the SZAN designation as means of determining the estimated age?

I thought the bigger the number the newer the machine is.Since it is all numbers after the first letters which are the same in all, smaller numbers should mean older machines.Am I wrong?

I own the same Honda GX 270 engine on the same snowblower.  I use the dedicated socket from Honda to turn the plug after I break it loose with the 1/2" drive socket wrench and its spark plug socket.  I agree that beginning the threading process is best done by hand, then use the Honda wrench which is too flimsy to break loose the plug or tighten it without risk of cracking the ceramic of the spark plug.  You need to become proficient at this task because the oil you must put into that spark plug hole before storing the machine for the off season requires the same spark plug removal. To put the oil in the cylinder, go to a Pharmacy and ask them for a syringe used to measure liquid medicines, they cost very little, and they allow the oil to be inserted into that small spark plug hole WITHOUT making an unholy mess out of you and the engine.
