      Is there any place in the Los Angeles area to have the magnets on a magneto flywheel re-charged?

        Are you sure they need to be recharged? How old is it?

          What motor are you working on.
          If your motor was built after WW-II it will
          have permanent magnets. Trying to recharge
          them will only damage them and there is no
          repair. If you magnets are strong enough
          to make a spark increasing the magnetism
          wonk make a better spark. That is why you
          can take a coil out of one of these and it
          will make a really good spark in one of these
          with its tinny little magnets.

          A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

            It is makeing spark. This is a 1930’s PR racing engine. Runs on Methanol. 30 cubic inch. I was told if the magnets are fully charged it will help it start easier. Although, it does start quite easily so I may be wasting my time and maybe creating more trouble than what I think I’m gaining. Thanks for your input.

              increasing the magnetism doesn’t increase the strength of the spark.
              How fast the magnets pass over the coil does. The faster a magneto
              spins the stronger the voltage. Its why they still use magnetos in these
              things.

                Thanks for your input, I think I’ll leave it alone. I’m heading to the Nationals in DePue Il and was looking for for any advantage.

                  I think most everyone here would like to see that thing run.
                  How about some pictures and maybe some video when you get back?

                    Yes! Very much! Video of it running would be great! Pics better than nothing.

                      The PR was built with soft iron magnets in the flywheel. A "keeper" should be placed across the magnetic poles whenever the flywheel is off the motor. Other wise the magnet may weaken if the flywheel is dropped. . . 😉
