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.

Question
Blows fuse when trying to start.It runs only if you cross the solenoid and squirt gas into it but now it doesn't run.The yellow and white with red stripe was loose and the two black wires were loose on the key switch. So i switched them around and tried starting it. it would'nt fire so i put it back the way it was but it still doesn't run. If i undo the wire that is red with a white stripe at the solenoid it doesn't blow the fuse but if i unhook the coil wires it still blows the fuse.  

Answer
Blowing fuses is usually associated with a direct short to ground.  Have you checked the wire harness for a bare wire or broken wire insulation?  Shorts usually happen when the wire harness turns or is routed through a hole or under the frame.  Another common short located is direcetly behind the starter.  If the starter is removed make sure the wires are not pinched when replacing the starter.  The OHV engines have a diode harness between the coils.  Are the diodes shorted?

If you send me the engine model, type and code numbers I can look up the harness.

Eric
