Thanks for the welcome! Great pic humfrz. I have attempted to get the rock through the valve control assemblies that are on the front of the case. In the process I ended up pushing it down further so it's now below the bottom right pulley in humfrz' pic. I've been using a 3mm borescope but now the rock is out of sight and reach.
Possible name change since I'm the first?
RockyMotor86?
