The mower is red.

J19LM

Do you know the item or model number?
J19LM is the most common but a few carry the RJ19LM

If you don't have the number I would recommend the 71/33943 E3.10 Spark plug, it's very universal and has a pretty awesome life span.

I like the One-Tug-Plug myself. :)

Yep, sounds like the majority of my customers. Then they look at me like I'm supposed to know everything! Of course, if it's a Briggs engine... J19LM!

What is the difference between a J19LM and RJ19LM plug?

Not having the "right" spark plug is a PLOT to make me buy a new mower!

Is there an upgrade kit to convert my mower into a self-propelled mower?

I don't like this white grass bag.

I'd like a black bag to go with the mower.

You don't sell bags at the store?

 RJ19LM has a resistor to reduce RF interference.I always considered them interchangeable with J19LM.For years and years 143 source Craftsman engines always used a J8.But I thought Briggs engines used the compact CJ8.Maybe my memory is starting to fail.

Ah! The resistor is not a "requirement", more than a convenience to avoid annoying the neighbors.

How do I get the spark plug "out"?

posted on September 05, 2009 at 05:50PM
 

Is there a special tool?

It should have been "included" with the machine!

Is that Metrical, Fractational or a special Sears size?

These new machines are so complicated!

Ah yes... I get this question all the time. The answer I give my customers everytime is "About 3-4 dollars."

If I break the porcelain on the spark plug, will Sears give me a new plug?

Can I upgrade my tires?

Phone call, I hope it was a joke

Well, if Sears is not going to "stand behind" its equipment (including spark plugs)...

What kind of tire upgrade?

posted on September 06, 2009 at 02:10PM
 

The thing won't start. Sears should do free Service on it. All the Craftsman stuff is life-time warranted...  I've owned the red mower for only around 6 years.

Where would I find "gapping" information for the plug and what is the torque value for putting a new plug in?
