I know the Lycoming 235 is not the most popular engine fitted to RV9s but I know there are some flying.
We've done a little work measuring components for these with the help of one of our clients. We found the intake manifold bolt pattern is the same as the Continental O-200 so we're able to use the 45mm throttle body developed for that kit to fit the Lycoming.
Most O-235s never came with injector ports in the tops of the cylinders so we'll use our AV Lycoming injector mounts installed in the primer ports instead.
We'll use the standard Lycoming 4 cylinder fuel block on these as well.
We also have some lower current draw pumps to go with these smaller engines.
I hope to have some photos of the install in early November to share with those who may be interested.
