i searched and read but still don't have an answer.
1966 2010 landlord 10hp briggs with electronic module replacing points otherwise stock.
i rebuilt my 10hp briggs 243431 since it burned alot of oil. rebuild went very well and included a new 2 leg armature/coil .
no spark at start up. checking plug wire gives a negative polarity..?? ??
i reversed the module polarity(switched wires) and it now has spark and runs great but starts hard.
why did this happen?
does the starter/generator need to be polarized to run a certain direction?
i need to check which direction the motor is running! (clockwise when viewed from sitting (before the rebuild), if i remember correctly)

You say a new 2 leg armature/coil was installed. Was it a Briggs part #398811 by chance?
