It looks as if the hop 'floats' and is located by the nozzle and the front of the gearbox, so alignment shouldn't be an issue unless the wiring has got jammed against it somewhere.
It is a floating hop system, I think it's putting strain on the nozzle when installed as it sits slightly higher. I'm going to try and space the rear of the gear box so it sits properly. I'll let you know how it goes. Thanks again!
