Received the prop adapter from CH, with the single bolt adapter. Had to machine the hole for the magnet, myself, but this was easy to do once I got the right drill and reamer.

I've run the engine now with Master Airscrew 24x10 (inexpensive place to start). I'm getting about 500 more RPM out of it then the Byron 3-blade prop, and what feels like a lot more thrust than the RPM increase alone must be providing - I expect it has alot to do with the stiffer blades than those found on the Byron prop.

I plan to try a 24x8 and perhaps a 22x8, next.

I have one question left. If you or anyone else has an answer, would like to hear it.

I'm looking understand if there is something wrong with my engine setup - it spits an unreasonable amount of raw fuel/oil from the carb. The engine runs great at all settings. I cover the right inboard wing, fuse side and gear with newspapers before running the engine (cowl off) - after 10 minutes of run time, the newspapers are soaked through to the point that I still get fuel/oil on the paint. This just doesn't seem right.

I've not seen anyone at my club having this problem on their gas engines, nor have I ever had this issue with any of my yard equipment (chainsaw, line/hedge trimmers, etc.). The engines on my yard equipment are of course equiped with air filter systems - perhaps this is the difference.

Any ideas?
