The photo showing the 216 mounted seems to show it skewed toward the right (passenger) side. The engine looks not to be perpendicular to the cowl. Also, it seems the alignment of the radiator to the fan doesn’t appear to be parallel? If so, there is something wrong somewhere. That misalignment is also looks to be shown in the photos with the 235. That is why my observation about a collision was offered. It would also seem, but not knowing otherwise, the angle difference from correct would affect the drive train alignment and lead to other problems?
