style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">I'm still sort of
new. Does W.O.T. = with out throttle? On 45 degree downlines of
medium length like the reverse Cuban eight from the top (Masters sequence),
I'd say the motor just unloads some. If it were lean, it might cut-out
for a second when throttling up. If it were rich, it might gurgle or
give signs of loading up. The 140 or 170 do neither. They just
increase in rpm as the throttle is increased. </SPAN></FONT></P>

style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">On the 140 setup (15%
C.P., 2 OSA5), I needed to lean the low-end screw 1/8 turn during the
2<SUP>nd</SUP> tank on the ground. This setting has held fine since, now
with 1.5 gallons through it. The engines will idle very low, however, I
raise it to 2000 for takeoff and flight. </SPAN></FONT></P>

you dive W.O.T at about 15 degrees or so ( simulating using windup for
extremely windy conditions) does the engine lean/richen/or just unload ?
With the 17-13 on the 140, I shortened 'till the richening was gone. That
was just under 1" gap from stock.</SPAN></FONT></P></DIV>
