Spark Plug Gripe

Recommended Posts

I decided to take out the spark plug on the MTD...another part that appears to have never been changed...well, turns out the base is bigger than usual. My socket would not fit around it and I don't have one that will. Why can't they make them all the same size?

I sometimes think that the companys are in with the engineers at the tool companys.This way they make it so you need to buy more tools,LOL Like those torks screws,why do we need those...the philips and slot screws worked good for years....

Acually, I was doing some work on the wife's car and had to go buy a torks socket. They couldn't stop at a set of screwdrivers. Steve

Spark plugs are most often either 13/16" or 5/8", Wisconsin engines were 7/8",smaller engines may be smaller. 'Torx' head screws do not cam out like 'Phillips' screws, Myself I prefer ' Robertson 'screws (the square ones). Don

Ok, being in the hotel maintenance field I came across a screw I've never seen before when I started at this hotel. This one holds the TV's down to the swivel base. It looks like an allen screw with a hole in the middle BUT this one didn't have 6 sides like an allen it has 5. I checked every tool shop, tv repair, and hardware store, finally had to file down a larger security allen socket wrench from 6 sides to 5 sides. Took me about 3 weeks of searching before I decided to file down the hardened steel socket and this took me about 1 1/2 hrs to get it precise. Now it sits right in my desk drawer under lock and key.

Thanks Jon, I bought a set of these that cost me $135 and come to find out that one I needed wasn't there BUT I have every other kind of security bit that's made. I've come to the conclusion that the only way I'll find it is to go back to the building interior designer to find out who made the Tv swivel bases.:D The tool I made will last me probably 20 years if I don't lose it so I'm not hurting now. It was those moments when you had a full hotel with no wrench and just hope you didn't have to change a tv or vcr.B)

I agree When I was young we had 2 sizes 5/8 and 13/16 Now there's a few different sizes... As far as the Torx, they now have what they call security type.. they are torx with a little tip sticking up in the center... I think they should of just stayed with a allen screws...

I had the same problem with my engine. Try my method, I ended up breaking off the porcelin head, and putting an 18mm or 19mm socket on it, soaked the threads with oil, and it came right out.

Hmmm, I will need to try that.

I HAD only two spark plug sockets. Neither worked on my Mom's lawnmower. I went to Wal-Mart, and they sold a three-socket kit (from Stanley, I think) that included the one I didn't have. Now, I keep that little kit with it's plastic holder in my toolbox, so I know I always have the right size. It wasn't very expensive at all.

The Spark plug that was in the engine was a Champion spark plug, CJ-8 I heard the Champion spark plug, J19LM was predecessor to the CJ-8.

I thought " the CJ-8 was made in the 70's on but the JI9LM was a newer plug that also will fit/replace the CJ-8 (at least I know it does on a Briggs cast-iron 16 hp). But I have been proven wrong before....

I believe that info to be correct, as I think I had saw it on Champion's website. This spark plug appeared to be original. There was no electrode, it was completly worn down to the base.

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
