I have had to repair my airbox as it split under the clamp.
Can anyone tell me how critical the airflow into the carburettors via the box is?
Do I need to ensure a smooth and equal airflow?
I suspect not as the quality of the airbox is somewhat rudimentary.
For information I made up some bid' tube and epoxied it into the existing airflow
tube. I have tried to make the entrance a smooth as possible.
Thank you.

Steve, you should be fine as long as the internal diameter of the tube
is equal to or greater than the internal diameter of the carb opening.

When I had a airbox on initial build I bonded alloy tupe in to exits to strengthen
them.

Steve,
The air entry to the carbs is quite critical and should ideally be smooth and tapering
inwards from a larger diameter, which the Europa airbox more or less achieves.
Generally a 2 degree inward taper will help to preserve lamina flow in
the runner, as is often seen on the runners of injected engines.
This is further evidenced by the adverse impact on carburation that sharply curved
SCAT tube and/or long parallel-sided runners has, such as on some Jabiru and
VW installations.

| Subject: | Nose Wheel Shimmy |
When landing on a hard runway I always get nose wheel shimmy. I've checked the
friction on the on the nose wheel fork and found no problem. Has anyone else had
similar problems?

I have never experienced any problems and have the friction set as per the book.
I do have a nose wheel spat, standard speed kit, and also hold the nose off the
runway until the authority of the tailplane is lost.

A little swipe of Nyogel 774VH on both sides of the fiber washer then
torqued to spec will solve the problem.
