Handyman Wednesday: Replacing Spark Plugs

Hi everyone, Kevin’s here giving Jess the day off and providing you with another Handyman Wednesday.

We had a sad moment this weekend.  We went to start up our power-washer, and it wouldn’t work.  It’s a really nice power washer, too.  Here’s a link to it.  We got it from Sears Outlet for $200 almost 2 years ago.  If you haven’t read this post from last summer, now’s a good time to.

Ok, back to the problem.  It wouldn’t start. We pulled, and pulled, and pulled.  This model doesn’t have a choke on it, so there’s not much you can do but check the oil, gas, flip the switch on, and pull (really nice when if it works).  Jess and I, after careful online research, decide to replace the spark plug.  If we could fix it ourselves, we would avoid the $89.99 fee Sears charges to fix it.  Spark plugs are also really cheap ($2-$5).

Signs you may need to replace spark plugs:

1.  Engine is very hard to start (or won’t start)

2. Engine will “miss” and not develop power it should

3. Backfire caused by un-exploded gasoline going through your muffler


Fortunately, this is a VERY easy repair.  Here’s the steps.

1. Find the spark plug.  It’s about 2″ (5 cm) long and should have a wire with a rubber head connected to it.

2. Pull off the rubber head with your hands.  It doesn’t require tools.

3. Get a deep socket and socket wrench and remove the spark plug.  This will take some turning as there are a lot of threads on a socket.

5. Go buy a new spark plug at your hardware store (make sure the numbers on the side of the spark-plug match).

6.  Put it on the same way you took it off.  Push the black rubber wire back on, and you’re done!

If it still doesn’t work, you didn’t need to replace the spark plug.  We had this happen, as we pulled and pulled to no avail.  So Jess looked at the manual and saw that it had a 2 year warranty! Hooray!  We took it to the local Sears Repair Center and dropped that puppy off.  In 10 days, we’ll get it back or get a new one for free!  I love Sears.


Have you ever had tools fail on you?  Why do girls go to the bathroom in groups (seriously)?  If money doesn’t grow on trees, why do banks have branches?  If you cut off a glowworm’s tail would it be delighted?  If scientists were ever going to figure out how to travel through time, wouldn’t we now be seeing people from the future?  If you don’t pay your exorcist, do you get repossessed?


We'd love to hear what you have to say!
