Hello. Thank you for choosing Just Answer. I will be happy to assist you. Did you set the gap between your flywheel and your ignition, after you put on your new ignition coil? If not, you will need to set your gap at 0.10"

You can use a feeler gauge, or you can use a business card for this purpose. We can continue from here.

set it with the card they provided, possibly wrong coil as the engine number is ***** legible

Thanks for your reply. Have you checked your flywheel key? Your valves may also need to be adjusted.
