And, Bob, you know, for the life of me I'll never understand the logic behi
nd that airbox. =C2-Not only is the entry into the airbox located in an a
rea of accelerating airflow (i.e., Bernoulli would say, reducing pressure)
on the bottom of the cowling, but it is so big that removing the cowling be
comes a nightmare. =C2-Then, there is installing the cowling. =C2-Then
getting the SCAT hose in place. =C2-=0A=0ABut, the real issue is losing b
etween .8 and 1.0 inches of manifold pressure. =C2-=0A=0AI've been flying
my own design on 626. =C2-This plane has pressure transducers with digit
al readouts that measure Static and Manifold Absolute Pressure. =C2-Flown
side-by-side with an identical AG5B and it's stock inlet and the minimum d
elta between the 2 planes is .8 inches with 626 always showing a higher man
ifold pressure. =C2-Plus, my airbox is only 3 inches high at it's highest
point . . . =C2-still mounted on the side of the cowling. =C2-Even wit
h an airbox that requires cutting into the metal baffle on the front of the
engine just to make it fit, it's noticeably easier to remove the cowling.
=C2-=0A=0A==========0A626 got new wheel pants this past
week. =C2-This is the umpteenth set of wheel pants I've installed. =C2
-The first, however, that needed the bracket for the rubber shock mount o
n the topside of the landing gear.=0A=0ALessons learned:=C2-=0A=C2- (1)
The parts book showed shims that fit under the bracket. =C2-Honestly, I'
d never noticed a shim . . . but I never really looked either. =C2-=0A=C2
- =C2- =C2- =C2- =A2 I got the thick shims. =C2-Nope. =C2
-Made the bracket too high. =C2-No shim was about right.=0A=C2- (2) T
he bracket that bolts to the inside that supports the inside of the fairing
arrived undrilled for the fairing mounting holes. =C2-=0A=C2- =C2-
=C2- =C2-=A2 OK. =C2-Now, how in the world do I figure out wher
e the holes are supposed to be????=0A=C2- =C2- =C2- =C2-=A2 F
iguring: Since the wheel pant has only pilot locating holes, I can make it
fit perfectly. =C2-Just match drill the two.=0A=C2- =C2- =C2- =C2
-=A2=C2-The first thing I noticed was the bracket is not the same
length as the one on my Tiger. =C2-It's shorter. =C2-=0A=C2- =C2-
=C2- =C2- =C2- =C2-=A2=A2=C2-This required corner nut
plates=C2-=0A=0A=C2- =C2- =C2- =C2-=A2=C2-During installa
tion, it became apparent the fairings do not have the same curvature as tha
t required by the bracket.=0A=C2- =C2- =C2- =C2-=A2=C2-Warp
ing the wheel pant into place (with brackets bonded to the wheel pant) I ne
eded to enlarge my 3/16 inch holes to 3/8 inches.=0A=0A=C2- (3) I had a l
ot of difficulty getting the left wheel fairing mounted due to it not confo
rming to the shape needed. =C2-=0A=C2- =C2- =C2- =C2-=A2 Th
e sides mounting to the inboard bracket needed to be pulled in well over 1
1/2 inches. =C2-=0A=0A=C2- (4) Nose gear: =C2-The pilot holes for the
tow bar holes on the nose wheel pant, if you select the axle hole as refer
ence,=C2-=0A=C2- =C2- =C2- =C2- =C2-and=C2-keeping the bracke
t parallel to the bottom of the wheel fairing, are off about 3/8 of an inch
. =C2-=0A=C2- =C2- =C2- =C2-=A2=C2-Match drill AFTER the
bracket is installed.=0A=C2- =C2- =C2- =C2-=A2=C2-For the t
op seal, DO NOT DRILL ALL OF THE HOLES AT THE SAME TIME. =C2-=0A=0A=C2-
=C2- =C2- =C2-=A2=C2-Make sure the seal is in place, locate
the two front holes, Drill, install rivnuts, attach with screws, THEN DRILL
THE REMAINING HOLES.=0A=0A=0A626 is 5 knots faster with wheel pants.=0A=0A

Ned,
Thanks again- I forgot to mention that I put a brand new master switch in also.
Throwing new parts at a problem is not the most cost effective way of troubleshooting...
but sometimes the quickest! Too bad neither part has fixed it...
