5Fits Sears Snow Thrower 536.881750  Sep 16, 2011
By BobW
This plug is an identical replacement for Briggs & Stratton 491055. Used in Sears Model 536.881750

Note that the Sears manual for this machine INCORRECTLY states replacement as Champion RJ19LM

5Probably the most common.  Apr 22, 2011
By Nancy Billings
This is probably the most common small engine plug out there. That being said, it's probably cheaper to purchase this from Home Depot, Lowe's, or your local car parts house. That's what I did.

5Briggs & Stratton spark plug  Jun 20, 2014
By Wayne Banks
The spark plug was just what my lawn mower needed. My mower is now working great. I would recommend this spark plug to anyone that needs to replace their lawn mower spark plug.

There isn't much to say about a spark plug. I have already installed it in my riding mower and it works perfectly. I change the plug in my mower every year and it keeps it running like new.
