You can rebuild them yourself or have them redone. If you rebuild yourself, you will need a proper way to adjust them. You cannot do it by ear or with a buzz box coil tester. You will need to have a HCCT, ECCT, or a strobo-spark. I rebuild them and would be more than willing to do them for you. With a good rebuildable core, I charge $40 each plus freight. Feel free to contact me directly at
[email protected], if you want to do them yourself and need guidance or if you want me to do them for you.
Thanks
