Bob -

I have a similar Don George engine.  I cannot give you fuel flows since my 
EPI 800 fuel flowmeter has never matched the fuel taken aboard after a 
flight.  I do lean at all altitudes above 3000 feeet (100 degrees rich of 
Peak) and always when taxiing.  

I did fly my engine for 10-12 hours with the timing as shipped and it had 
always run rough -- "new engine" people said.  The day I scared myself on a 
flight with a very rough running engine, was the day my timing test equipment 
arrived.  The engine was firing 33 degrees BTDC instead of 25 degrees BTDC.  

After fixing the timing, It ran much smoother.  Even more smoother and cooler 
after about 50 flight hours and even more smoother (perceived in the cockpit) 
after prop balancing and putting on the softer engine mounts.
