Replace the coils with new ones... they will be a "light green" in appearance. You will be amazed at the new life that your motor will have. When you are buying the new coils... you may want to purchase the following: points, condensors, spark plugs, spark plug wire and boots. It is a bit of a pain to get under the flywheel... Once you are there, it is good to have these items on hand so that you can get it all done. When you remove old coils, the point where they attach to the plug wires is often corroded. Remove the old wire. cut a new one to the same size and replace both. Now you will have the confidence that these are all 100% Try and use the "harmonic balance remover method" rather than the "hit me with a hammer" method to remove the flywheel.... It is a much safer route for a beginner. You will also need a torque wrench and a strap wrench to replace the flywheel and nut. I think the nut will need to be tightened to 45lbs. Double check that. Best of luck... it will be work the trip. It is a great little motor.
