Just when everything was completed according to the Assembly Manual supplied with the kit I noticed a part that had an PN number that was associated with the gear. A question to the factory returned an answer that the part has to due with a Service Bulletin issued last Summer! My kit was supplied with some (not all!) the parts to comply with this bulletin but NO instructions.
I can comply with most of the Service Bulletin but I have to wait (months) for the missing parts to arrive.
