The fuel venting problem was solved by not filling the header too full. Now
I'm having some vibration and high RPM's on takeoff. At around 400 ft the
canopy has a little shake and the motor "seems like" it has a vibration or
gurgle, then the rpm's shoot up from 3000 to 3600. It feels like a car when
you are driving and push the clutch in without taking the foot off the gas.
Pulling the throttle back and pushing the nose down makes it go away and it
doesn't do it again flying around the area. It only "seems to" do it on
takeoff. Carb heat on or off doesn't stop it. There isn't any shake in the
controls. Any ideas?
