Reinstalled the fitting on the oil filter spacer ring. Forgot the o-ring between spacer and engine case, had to go back home and get it. Finished putting that together, took the air cleaner off to see if that restriction might be a problem. Rolled it out, tried to run it, still a bit hesitant. Adjusted mixture 1/2 turn richer and it ran very well. Much higher rpm's possible. Did a little more taxiing around. Brakes good to about 1800rpm, got it up to about 2200 rpm. Brought it back and there was leaking oil at the oil filter and fitting I had just fixed. Could not tell if it was at the fitting or because the filter wasn't tight enough. Wiped it off, put the RH cowl on and called it a day. EAA meeting will be at this hangar next week, so I cleaned things up some.
