1. Assembled the stock Van's mixture control bracket assembly (Photo 2) and held it up where it's supposed to go (Photo 3) -- only to find that, on my engine, it will have to be extensively modified to work correctly. There is a large block on the sump case with an oil port in it (Photo 1), and this means I'll have to strip off the powdercoating, grind off a significant portion of the bellcrank, cut reinforcement pieces, and weld them on. Then the bellcrank parts will have to be re-primed and repainted.
2. Similarly, almost none of the stock Vans support angles will work for my throttle cable or mixture cables, so I'll have to get some mild steel sheet and fabricate my own. I might also have to remove the right two exhaust tubes just so I can mount a cable clamp for the throttle.
3. I also have to figure out how to reverse the orientation of the mixture control arm, which is currently pointing downward, but needs to be pointing upward.

And people wonder why it's taking me so long to built this airplane...
