5I'm currently cruising the K&A when without warning or any noise I have lost reverse gear. I have searched technical manuals and have deduced that it is a conical clutch system. I have disconnected my drive cable and tested it for movement. The cable operates freely. I carried out the following check with the cable disconnected. With the engine running I operated the gearbox lever by hand. It engages fwd drive ok, however on full movement into reverse the propshaft is barely turning. Is there any adjustment I can carry out which would enable reverse to engage correctly without affecting fwd drive? Any advice and help would be grately received
