Our RR90 was hard starting so I had a look-see at the switch. Man, one hell of a lot of carbon builtup on the brass nipples and the 7 contacts that they engage with. After cleaning I attempted to reinstall the switch into the barrel and found that her 3 clips that engage the plastic were in need of tightening. And then I dropped the switch and out fell 1 small bearing/bb. Anyone know how the switch gets put back together? Anyone have diagrams or pics? Thanks.
