I wanted to see if on my =20= carbureted engine, less than full throttle, would even out the EGTs. =20 As you can see in the graph it did. In the past, when I ran the test at full throttle, cyls 1,2 & 3 are =20 50=B0F LOP by the time cyl 4 reaches peak. The engine is running so lean = =20 at this setting that I can't stand the vibration. With the throttle pulled back 1", all cyls are very close to peak at =20 6.3 GPH and the engine is still running smoothly. I am 5 KTS slower =20 than at full throttle but have gone from 8.0 to 6.3 GPH. This is a 21% =20= fuel savings for a 3% speed loss. In a 4 hour (676 NM) trip, it would take 7 minutes longer and save 6.8 =20= GAL or about $28. You pays your money, you takes your choices.
