My dad said my coil from disturbator is very weak, it sparking yellow when i start cranking we did test it all seems so normal but about 20,000 ohm testing the coil postive and negative is kinda out of range from 12,000 to 20,000 ohms, should i replace it? or is there any way i can repair it? we did connect with coil throught sparking wires plugs and my dad use driver in the plug and no sparking at all, must be a bad coil. Is that right?

That resistance is outside of spec:
IGNITION COIL RESISTANCE [at 70°F (20°C)]:
Primary:
Between the A and B terminals 0.6 - 0.8 Ohms
Secondary:
Between the A and secondary winding terminals 13,200 - 19,800 Ohms

But if you're spark is not blue and aggressive, check ignition dwell (if adjusatable) and battery voltage. Yellow spark is a weak spark, and may misfire under load.

we did recharge the battery and jump start too. what u mean misfire under load what should i do? please help me to find out what should i do? becuase i need it running before end of the month. My dad said he checked everything wires and stuff fuel pump still good and smell gas and everything test all was fine and my dad said i should buy coil ingiton should i buy it? or something else?
