If you have dual ignition, for sure, run it till it quits. I have one and it is working fine. Before I got my inspection, the inspector did some research on it, and sent me this note about it:
Mr. Heath, The slick 4216 has an AD on the coil. It appears that the serial number of your mag does not apply. However it would be helpful, if you could get a local A&P to make a log entry to that. The AD is 81-16-05. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2007 - KR Gathering There is a time for building and a time for FLYING and the time for Flying has begun.
