## Questions & Answers

**Q: Have a 2012 troybuilt riding mower with a 17.5 hp engine. what spark plug does it take?**
A: you need model # of mower and type of engine, ie: Kohler, Braggs, Honda, etc

**Q: Does this replace rc12yc?**
A: No the thread portion is to long

**Q: Will this fit a john deer js40 self propelled walk behind mower?**
A: Yes, I think the B&S 491055S will fit the John Deere JS40 mower.  The John Deere part number for the JS40 spark plug is M78543 (JD Model JS40 maintenance sheet).  I found 4 replacement plugs for the M78543 spark plug from a cross-reference website:  Brisk 1326, Brisk DR17YC, Champion 71, and Champion RC12YC.  It is important to measure the length of the threads on the original spark plug and compare it to the new or replacement plug.  If the threads are too long you run the risk of the piston impacting the bottom of the spark plug; ruining your engine.  I've used the Champion RC12YC on my JD E100 riding mower that has a B&S engine with the B&S 491055S spark plug.  The Champion RC12YC is one of the replacement spark plugs for the 491055S.

**Q: Are these spark plugs b&s plugs or off brand plugs? thank you  be safe out there**
A: Hi they are briggs and Stratton brand.
