| Subject: | Coming Soon - The List of Contributors - Please Make A Contribution |
Today!
Each year at the end of the List Fund Raiser, I post a message acknowledging everyone
that so generously made a Contribution to support the Lists. Its my way
of publicly thanking everyone that took a minute to show their appreciation
for the Lists.
Please take a moment and assure that your name is on that List of Contributors
(LOC)! As a number of members have pointed out over the years, the List seems
at least as valuable a building / entertainment tool as your typical magazine
subscription!
Assure that your name is on this year's LOC! Show others that you appreciate the
Lists. Making a Contribution to support the Lists is fast and easy using your
Credit card or Paypal on the Secure Web Site:
http://www.matronics.com/contribution
or by dropping a personal check in the mail to:
Matt Dralle / Matronics

Livermore CA 94550
I would like to thank everyone that has so generously made a Contribution thus
far in this year's List Fund Raiser! Remember that its YOUR support that keeps
these Lists going and improving! Don't forget to include a little comment about
how the Lists have
helped you!
Best regards,
Matt Dralle

Jan,
Go to Rotax-Owner.com <http://rotax-owner.com/> and under
support/bulletins you=99ll find Engine Manuals. Find the
installation, operators and maintenance manuals and download them. In
there you=99ll find information on how to check your valve train
for entrained air and check for any damage.

Should I now undertake investigations for damage and if so, what should
I be doing to put this worry behind me? Rocker covers off and look at
valve spring caps? Check magnetic plug? Prime the oil system again to
purge air out of the tappets?
