Go for it. It will make everything better,,idle, throttle response, no timing lag/fluctuation. Make sure your battery is fully charged and your starter is in good shape and you will be good to go.Some have complained about kick back while starting. I have found that the battery or starter are usually causing those type problems. You can also wire the ignition to be turned on while spinning the motor if you want to run timing on the higher numbers.. Try it,,if you don't like it, you can always put it back the way it was..
