<DIV><FONT face=Arial size=2>The cold rpm is OK with the restrictor in place,
removing could increase a 100+, depending on engine wear. The
symptoms suggest excessive disc valve / backplate clearance, although I don't
understand the attitude issue - maybe just because it's WOT there. (Oil seals it
when cold - leakage when hot reduces boost - less air = rich, leaning won't help
as air volume is low.) Early versions suffered wear at the retaining screw
washer / backplate interface - later models used a better design (similar to the
AC). </FONT></DIV>

<DIV>Hey everyone. Asking for a friend. Have a 140DZ. It has
several issues we can't figure out, wondering if anyone has any
suggestions.</DIV>
<DIV> </DIV>
<DIV>16.5X12W prop, Magnum DZ fuel, Hatori header and pipe, OS F Plug.
Only get 8300RPM at start but as the engine warms up it noticably drop 3-500
RPM. The idle is reliable as well as transition so don't think it is the
pump. The high needle is 1.5 turns out. Leaning it only results in
a drop in RPM. The problem is it goes RICH on vertical lines or vertical
radii. The plane slows so much it is hard to fly well at that
point. The smoke doubles after going vertical.</DIV>
<DIV> </DIV>
<DIV>Any ideas??</DIV>
<DIV> </DIV>
<DIV>Secondly, Joe wanted me to ask if the restrictor in the carb could make a
big difference if taking it out??</DIV>
<DIV> </DIV>
<DIV>Thanx in advance</DIV>
