I suspect those Remflex gaskets were made to my specs several years ago and=
 were intended for a hogged out Weber flange set.  They'll be very thin nea=
r the top of 3&4 if they're the ones....

    Bill,
You were right but I don=E2=80=99t have a good solution at the moment. Only=
 # 3 reacted to the carb cleaner and that suprises me a bit.
I have the thick remflex gaskets in there. One side of the intake manifold =
on # 3 had barely any contact with the gasket.
The remflex and the Moss gaskets have 1-11/16=E2=80=9D inside diameter open=
ings at the intakes. My cannon manifolds are 1-7/16=E2=80=9D
and the cannon=E2=80=99s don=E2=80=99t have a lot of meat for bearing surfa=
ce around the lower area=E2=80=99s around 5 o=E2=80=99clock and 7 o=E2=80=
=99clock.
As best I can tell though it was actually leaking on # 3 at 3 o=E2=80=99clo=
ck right next to the clamp bolt.
I could actually look next to the clamp bolt and see where the gap was.
I need to either find different gaskets with a smaller ID or make my own.
Have you, or anybody had success at making their own intake/exhaust gaskets=
 from regular gasket material ?

Sounds like an air leak somewhere. Perhaps it gets overcome at full throttl=
e or is worsened at those specific RPMs because of harmonics in the vibrati=
on of the carb. Might be a crack or flaw in the carb, but more likely it=E2=
=80=99s in the mounting, either O rings or some other flaw. They can be har=
d to detect and locate. You could use the carb cleaner method=C2=ADspray a =
little at each joint or suspect area and listen for changes in engine sound=
. I=E2=80=99ve used the ultrasonic detector I use for finding leaks in surf=
boards to some effect, a leak sounds like a calliope, but there=E2=80=99s a=

   I just installed my webers and I=E2=80=99m running into something not co=
vered in anything I=E2=80=99ve read so far.
At cruise speed which I do on the street, 2500  -3000 RPM my exhaust gas te=
mps on # 4  are 100 plus degrees
over # 1and will climb to 1400 if I stay at that throttle setting. Under wi=
de open throttle they equalize and seem
to settle in at about 1300.
However, I think this may be symptomatic of my other issue. When I=E2=80=99=
m tuning the idle air screws, open them up until
it starts to miss & so on, I can get a predictable stumble from three out o=
f the four screws.
The screw on # 3 has no effect on the idle no matter how far I run it in or=
 out.
Also , when I put my syncrometers on #=E2=80=99s 3 and 4 they are significa=
ntly different.
I=E2=80=99m not going to get my dyno tune before the first race in two week=
s so I=E2=80=99m left to figure it out on my own for now.
Any help would be greatly appreciated,
