It sounds to me like you are messing with the wrong side of the motor.
There are not 3 sets of points.
What you described is the centrifugal clutch.
Look on the other side of the motor.
I am thinking you have either too much gas... or not enough... or the spark plug is getting gas fouled from puddled fuel.
Or the compression is not high enough.
How old is the gas?
Or the exhaust pipe or exhaust port is plugged.
Use that guide slowly and methodically...step by step.
