I seem to be the only other person who has had several bad experiences
with flaps over the years. Check the spring and make sure nothing is
binding on the linkage. My Puma was running hot a few weeks ago and I
blamed my leaving the parking brake slightly engaged. Turns out the
linkage was rubbing and sticking on the top of number one leaving the
flaps about half open. Now they are open and will stay that way. No
comments from those who worship the flap gods. I believe the biggest
enemy of my engine is heat not cold.
