Subject: RotaxEngines-List: Carbon Monoxide and 914
From: rparigor@suffolk.lib.ny.us


Has anyone measures carbon monoxide on 914?
perhaps used one of
these:

BTW Bing sells exact same model for less. Any details and findings would
be appreciated.

Rotax 914 when creating "War Emergency
Power" enrichens fuel mixture by adding a little bit more pressure to
the float bowls over normal airbox pressure. This accomplished by a
"hand" cupped facing incoming airin the airbox that raises
pressure. The enrichment solenoid that is controlled by TCU (in my case
also a "rich" button) plumbs either airbox pressure or slightly
higher than airbox pressure. On earlier airboxes the "hand"
needed to be adjusted, think it was fairly touchy to get it right. The
later airboxes use a different design, don't think as critical. Bottom
line is Rotax states that when equipped witha new style airbox you
need to verify that when creating "War Emergency Power" you are
running rich enough. They want you to use a Carbon Monoxide tester.
