Thank you for allowing me to assist you, my name is Joe and I will be happy to assist you with your concern today.

Have you tested spark to see if you are loosing spark or another problem?

I am just seeing if you still need assistance with this problem? The reason I ask is because I see that your question has not been answered sooner and I wanted to make sure if you still needed help.

In some cases a question may sit due to several different reasons. My objective that I wish is to make sure that if you still need help that I can at the very least reach out to you and attempt to help you.

At this time please feel free when you are ready to reply back to me and ask to continue working with me, another expert or if you no longer need help please just let me know exactly what you wish to do.

Expert:  Joe replied 1 year ago.

DO you have spark without removing any wires?

I am sure there is spark connecting wire after it starts it runs fine. Do you think it could be a weak coil?
Expert:  Joe replied 1 year ago.

I am referring to it having spark before you touch the wires. You need a spark tester to check this.
