Ellison had a whole page about vapor lock on their web site. Do you have
any pictures of the installation on your type 4. If so, please direct me to
them or send to me off net. I have not flown much in the last few years and
after changing to the Revflow removing the Posa, I am still not satisfied
that I am making full power with the Revflow. When the RPM stops
increasing, the EGT starts to climb. That tells me that the engine wants
more gas, or a better mixture. I have changed needles and even tried to
custom carve several. I still seem to run lean at wide open throttle.
Thanks
