BOATFIXERGUY Posted November 4, 2007 Posted November 4, 2007 is it normal to burn 20 gal an hour for a 280 fx 1985 ?? thank you No....way too rich! Do you have an EGT or just cylinder temp? For rides we run a little rich at 1450 deg to help keep it cool. Normal flight is set at 1550. At the 1450 range, you'll go through more plugs, but save your engine in the long run. Quote
