In case anyone didn't know, Slick just revised SB2-19 from October 2019. It covers faulty impulse couplings which are installed on 4300 and 6300 series magnetos. Meaning anything bought new during the period from February 2015 to February 2019. Four years worth of bad couplings are out there.
The good news: there is some warranty coverage on this one.
