| Magneto Expert Re Setting of Magneto. TBB2/L13813. Mr Royce. 13.8.13. With reference to your enquiry concerning the setting of our standard magneto, I understand from Mr Platford that our standard practice is ¼" to ½" lead on the flywheel. He informs me that this setting and also the 1" lead setting on 2004 were adopted as being the best by experiment for all round power on the dynamometer. XH30 | ||
