On this engine though the carb is very asymmetric in shape, it doesn't show so well in the pictures above, but the section with the airbleed screw is sitting on a bulge on the carb. This bulge puts the screw very close to the prop, and it will also hit the cylinder if one rotates everything by 90°.
When you turn the carb 90 degrees, do you recommend putting the needle valve into the prop arc, or into the cylinder?
Agree on engine colors- but there are a few exceptions. The purple West .50/.52 for example. Hmm, what else now..
