About Eric A. Jones
Expertise
Lawnmower Repair . Certified Master Service Technician from B&S. Have 13 years experience on B&S, Lawn Chief, Weed Eater, Echo, Peerless, Wheel Horse, Snapper, Atlas, MTD, McCulloch, Homelite and many other numerous brands. Specialize in electrical repair.

Experience
Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. I received a scholarship from the Air Force and am currently pursuing another degree.

Subject: No Spark on Engine

Question
I have a Briggs & Stratton Quantum XM 4.5 HP engine with no spark, I have removed the recoil and magneto/coil assembly and cleaned the gap and adjusted to 0.006" and still have no spark. How can I test the magneto/coil assembly or do i need to remove the flywheel and test components below?


Answer
How old is the engine?  Dis-connect the small wire on the under side of the coil and check for spark.  If you have spark the coil is fine.  If no spark, odds are 99.99% the coil is bad.

Let me know the age of the engine before buying a new coil.  The first two digits of the code number is the year the engine was built.

Eric
