Hey Guys,
A relatively quick way to tell if you have leaks in the intake manifold is
to do the old Citabria exhaust manifold trick. Remove the carb, set up your
shop vacuum to "blow" and attach the hose to the intake manifold. With the
air blowing into the manifold coat the all the various fittings and joints
with a mixture of soap and water and look for bubbles. I've found mine
leaking at the rubber boots where the upper and lower intake pipes connect
using this technique.
While at Jabiru school they told us to put the black "gook" on about 1/4"
before the pipe bottoms out when inserted into the splitter. When you push
the pipe in the rest of the way the "gook" will push into the joint and help
the "o" ring seal.
Hope it helps!
Regards,

The Black "Gook" is #2 gasket sealer, from permatex or versacem.
Hope that helps
