Good news trev,send the 82 and 115 over for a run in..i'll send them back,promise.
Dave re the run in on the 90 twin was out in the shed lazily re reading my 182 twin manual again because i don't think i'm confused enough yet.Apparently it says i never should have run it over 4000 for the first twenty minutes then onj the second tank you can start it at full throttle and after a minute or two lean the twin main needles to peak rpm occasionally.After that you are supposed to fly it at less than full throttle for about ten flights,that never happened.Why so different for two bolted together 91's and a single one? i'm happy i don't have the manual in front of me to quote,no wonder people drink beer.
