Rougher Idle with Carb Heat on
in 912 / 914 Technical Questions
6 years ago
I have a Rotax 912 ULS in a Tecnam Bravo. 90% of Bravos have no Carb Heat, but mine does. Just had a carb sync done about 10 hours ago. Runup is normal even the Carb Heat preflight check. As an old taildragger pilot, I like to dead stick landings from base. I noticed a slightly rougher engine at about 2350rpm idle during the dead stick approach. Any ideas if this is normal for a 912 ULS with Carb Heat?. Can't ask any Bravo owners since I can't find any, same with mechanics that are familiar with the Carb Heat.
