#### Thank you. I have also reconnected the wires at the individual coils and
after running the engine today, it is doing quite well. I wish I could say
what is different, but I will fly in the morning. I have wrapped the exhaust in
an attempt to provide better cooling in the cowling and will see how the
engine performs after this flight. I fully expect the problem to re -- emerge!
