| Subject: | 914 Carb Drip Trays |
Attached is an article not yet published in the Europa Flyer that shows a modification
that allows easy removal of the carb bowls on 914 engines equipped with
the old style drip trays that are secured under the carb mounting bolts. Having
this mod in place saved many hours this summer when I had a carb bowl gasket
sealing problem!

| Subject: | 914 Carb Bowl Gaskets |
We had a problem with the carb bowl gaskets leaking after having the carbs rebuilt
by a Rotax repair shop. The gasket P/N 830 727 has changed over the years.
The gasket supplied when the carbs were rebuilt in the summer of 2016 must
be allowed to expand to seal properly. The maintenance manuals do not have instructions
for this. The manual does specify the torque is 48.7 in lbs.
Lockwood's procedure is to soak the gasket in gasoline for 4 hours, install and
torque. Return in 24 hours and recheck the bolt's torque.
Roger Lee says to use white grease. Lead Edge Airfoils says the only approved
lube is lithium grease. Both say it is necessary to re check the bolt torque
after a few hours.
In our case we soaked the gaskets per Lockwood instructions and used a light coating
of "fuel-lube". Roughly 6 hours after install we checked the bolts and
had to retighten. Re checked again after 24 hours and they had not loosened.
The carbs have performed properly up to 16000 ft since.
