I have a 130200 5 HP Briggs & Stratton Engine made about 1977 on a rototiller and I'm changing the points and condenser. I've searched everywhere and cannot find the spec for the Gap Can somebody help Thanks Bob
I don't think a one inch point gap will work. :-) Usually .020 gap will do, if I remember from 35 years ago. 294628 used to be the part # for the points on a Briggs. Another forgotten part number would get you the little phenolic plunger that pushes the points. There is a line around the plunger that indicates when it is worn down and needs replacing. While turning the engine, if the line disappears into the block's bearing boss, then replace the plunger rod, as it affects the engines timing events. Also, the first two digits in the engine number represent cubic inches displacement. End of
Voltage doesn't "bridge" the gap. The OPENING of the points collapses the coil's field, causing it to fire the plug. The gap in this case determines ignition timing, and also point dwell, which determines coil saturation, which affects coil output.
My "Small Engines Service Manual" says that the 130000 series has a 2
9/16" bore and a 2 7/16" stroke for a displacement of 12.57 cubic inches. It goes on to say that "...the breaker contact gap is 0.020 on all models. Condenser capacity on all models is 0.18-0.24 mfd"
