Roger,
This works fine for the 912 as shown. The early 914 engines were fitted with a
massive drip tray which prevents loosening the screw on the carb socket to enable
removal of the carb. Also the turbo airbox is quite rigid due to the hose
from the turbo. And the 914 bowl is held in place with a bolt, not a spring
bale. Trust me, I have tried to get the bowls off in the field and have never
been able to.
With the modified drip tray, it is easy to remove.

Roger,
I think the float bowl seal required for a 914 carb is more critical than that
on a 912. On a 912 the float bowl is vented to atmosphere. On a 914 the bowl
is pressurized and any leak will cause a problem, especially when flown at high
altitude (over 12000 ft density). There have been 2 or 3 variations in float
bowl gaskets over the years. The current gaskets seem to compress after installation
and require that the bolt be re-tightened.
I was stranded in Santa Fe, NM last Fall. The problem was leaking float bowls.
I could see the fuel stain in the drip trays. I had a new set of gaskets and
we changed them. We just rubbed the new ones with Fuel Lube and installed.
The new ones leaked immediately. We then talked to Lockwood and learned of the
soaking procedure. We got another set of gaskets and installed them following
Lockwood's instructions. Re-tightened them after 6 hours and checked them
again after 24 hours. Then we flew the plane and have had no further problem.
