What is air gap between magneto and "flywheel", Briggs and Stratton Model # 10A902-0178-01? Mike Rudolph, XXX@XXXXXX.XXX
Optional Information: Make: Briggs & StrattonModel: 10A902-0178-01 Already Tried: .006"
For best performance, it's as tight as you can get it. A dollar bill folded in half works great. The book adjustment is .010"
You can't adjust a Briggs coil so that it won't fire. The advantage to having it tight is that it advances the spark a little resulting in a little better performance at operating speed. If it's not firing, you have a different problem. Thanks, PK.
