Finally got the plqane out to the field, got it started, squeaky tight engine. After a couple minutes, started blowing exhaust out the cylinder head, couldn't keep it running. Three head screws on the Super Tigre loosened up, and the idle stop screw joined one of them in the engine compartment. Had to take the plane home without flying, and remove the engine in order to retrieve them.. Never had that problem with a Fox, or any other engined I've ever had. Still, a lot of people I know wouldn't have any other brand. Maybe next week. Should be loose enough now to start leaning it out.

Also kind of funny, I set the engine into place using a Dubro 2 1/4 inch spinner, but I didn't have that size in a color that matched the plane. Found a Goldberg spinner in a matching blue color, and I prefer the bolt-together spinner over the snap-together type anyway. However, turns out that the Goldberg baseplate is a little thicker, and rubs the nose bulkhead. Can't use it. Luckily, I happen to have a white Hillcrest spinner, in which the base plate mounts between the prop and the prop washer, and gives adequate clearance. Hopefully, it's probable 20+ year age shouldn't have weakened it.
