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
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.

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
Dirt and I are exactly the same age.
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"
