Installation of the Jabiru engine mount is known to be tricky.
And it got trickier: the bottom, passenger side bolt now has even less clearance for the nut installation.
The picture above shows, on the left, my engine (3300, 4th gen). I had to put the nut in place with long tweezers and slowly rotate until the thread engaged; then I used an open wrench to tighten (a box wrench would not fit).
On the right is a screen grab from the HobuildersHelp video, showing a much larger clearance: one can even use his/her fingers to put the nut in place... (the video was done before gen 4 was announced).
