Has anyone measures carbon monoxide on 914?perhaps used one of these:http://www.eastwood.com/digital-exhaust-co-analyzer-with-pulse-pump.htmlBTW 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 air in 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 with a 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.Ron Parigoris [quote][b]
