The ability to adjust the engine may be dependent on the size and placement of the engine tab holes. I'll have to pull the engine out and look at it more closely.
It depends entirely on the size of the holes in the tabs, I've been lucky with the IDM engines and I've also seen Novarossi installed with proper gear meshes. the bottom mounts have a tiny bit of play as well, you may have to loosen all 4 screws to get it right.
