&= nbsp;Yesterday I started to run a LOP survey... went to 7000 ft. where 2400= rpm
could get no more than 24."=0AMP, WOT, and leaned until one EGT (#= 2) peaked, and
began to reduce, whiole the other EGTs kept increasing.&= nbsp; Showed about 10.3
GPH,=0Abut wandered a little down to 10.1 = and back up to 10.3.
 Slow leaning immediately resulted in a defini= tely noticed reduction of power,
and=0Aenriching a little restored it. = Could not lean any further.
 The other three cylinders were still d= efinitely ROP.
 So, it looks like=0Amy Airflow Performance injector= s (which have to be in the
primer ports) may not all be the same diamet= er (.022, .028, 0r=0A.032).  
 An initial static flow tes= t of the injectors showed all about the same flow.
 It looks like i= f I can replace the=0A#2 nozzle with the next larger size, i
could then= continue to lean ALL four cylinders and EGTs further than `10.3
gph, @= 24/2400.
 I=0Awould like to get a lot closer to 8 gph.
 An= y comments of similar experiences or suggestions would be=0Aappreciated. Thanks.
