When I pulled my gearbox off- I checked to see if the prop shaft was bent, which it was not. I did not check the crank, my logic was if the prop shaft was straight the crank should be straight too. When Aircore rebuilt the gearbox I am pretty sure he replaced the spring washers behind the dog gear(there was a update on those I think) and when I talked to him a couple of days ago he remembered some galling(or marks) on the dog gear. My rough running issue is vibration, started by gearbox chatter below 2500 rpm. I will try to get some video of it so it can be better understood. Thanks again for all your input.
