How to decide which ignition coil is best among velwy

[chamjiee]

Hi have few ignition coils lying around. How do I know which one is the best?
How do I know it? Is there some value that determines it?

I am confused because one ignition coil for cHondaz 70 is having 0.6ohm primary coils resistance and 4.7K ohm for secondary winding.

Another ignition coil from Honda cg125 is having 0.4ohm primary winding resistance and 3.04k ohm secondary winding.

Size size the coil from 70cc engine is much bigger.

I assume it's the ratio secondary/primary that should matter as that's the voltage amplification ratio?

In all honesty mate put your wet hand on the plug when it is in the lead and earth on the frame and kick her over. The bigger the "F@$K ME" is means you have found your coil. I spent a fair bit on a chp coil and in all honesty I gained nothing from it. I've put China could on hap 2 strokes and same same. Pretty much all the same. I use the one that usually has the proper mount for the frame.
