Hello,
I have a 912 ULS. I have noticed that when I'm at 3500 feet or higher and I pull the throttle back (mid 4000 rpms or lower. "Chop and drop") and shove the nose over for a rapid descent (to get below a cloud deck for example) I will get a whiff of fuel. This does not happen if I descend with power at 4500 rpms or higher. I don't like to "chop and drop" and I try to avoid doing it.
1. Where is the fuel coming from? Vent line? Air filter?
2. Why am I getting a fuel smell under the above mentioned conditions? Does the carb fuel bowl flood with a rapid reduction of throttle?
Thanks,
Jack
