This is my first post here. I have just begun my journey to build an RV-6A and it will be my first aircraft build. I have just put a deposit on previously started QB kit without too much work done on it. I also picked up an O-320-B1A engine this evening that I will be overhauling (top end already done).
While the engine is a B1A model from a twin Comanche, the sump is not what I thought was on that model. This sump has a vertical carb inlet on the bottom. However, this opening is positioned at the rear of the sump and not in the middle as I thought was the most common for the 320. While this image is a sump for a 235, it looks identical to mine.
I am hoping someone can let me know if this will work with the RV-6A. I won't be picking up the kit for a couple of weeks, so I have no way to measure clearance. From pictures, it looks like it will be close. I fear the carb may interfere with the point on the mount/frame where the four support tubes meet up with the front gear strut.
I would appreciate any guidance that you could provide.
