I finally got the bearings and ring for the OS Max 40FSR from 1974, mounted it to a test board I made, bolted it down to the Northampton test bench and started it up. It took 10 seconds of spinning with the starter before it started to cough and ran on it's own, but it didn't seem to want to advance throttle very quickly. Had plenty of compression though. I suspect it's just a low speed needle adjustment but it doesn't have one, instead having what I'm told is a bleeder screw. How do you adjust these? If the engine is hesitating, as seen on the [link=http://www.youtube.com/watch?v=KN5JXmEzHd8]video[/link] I captured of this test run, when throttling up, I'm told it's flooding with fuel, so I want to lean it with the bleeder. What direction would that be?

I also had a few screws come loose, one an engine mount to the firewall, which came all the way out, and one of the nose gear screws into the firewall. I removed them all and applied threadlocker and re-inserted them and tightened them back up.

The fuel compartment cover on top of the plane blew off in flight a while back as it was only held down by a single flimsy self tapping screw, so I built a new one with some ply, covered it with Aerokote and put in two heavier screws to hold it in place. It's not going anywhere now. I need to cover the entire cover with a second layer of Aerokote to clean up it's appearance and cover the leading curved edge.

The Aerokote is starting to peel in certain areas - see the photos. I'm thinking of peeling it back, trying to soak it with alcohol to draw the fuel out and blowing it with hot air to dry the wood before applying new Aerokote. Is this a good idea?
