Thanks Bill, that is some interesting information to consider.
The reason I select carb heat cold on late final is not
damage to the engine but Rich Cut, and even then that is not a
problem if you are landing, but on T&G's and on short fields
can be a decider if you end up in the hedge ( or at Henstridge in
the fence or girders), so I my norm is Carb Heat Cold on late
final and a gentle cycle of the throttle to check its still there.

Joel Ventura did quite a detailed article on Prist
Note: Prist wont stop carb ice, which comes out
of the atmosphere. Prist deals with water already in
suspension within the fuel.

All your comments, experiences and knowledge no doubt
turned out to be a real education. I don’t know about
y’all but icing is normally not a discussion item. I’m
glad I took the chance to post the article. Learned more
than I thought I would. And thank you all for “Your
I must admit I was hoping for some info regarding the
use of Prist. I did actually use it in the Quickie for a
time. Reckon it did ok..that was several years ago. My Q
does not have carb heat nor does the carb have access to
outside air, only hot air off the engine and is why the
interest in the Teflon coating. The carb on the newer
Onan sets higher so to accommodate a new heat box I would
need to make a new cowl bump....like that was gonna
happen! Not surprised no one had much to say about it.
Like Jay I’m sure ice will form Teflon or not but I’ve
never used a Teflon coated anything that anything would
stick to it. I once froze water in both a steel pan and a
Teflon one. Guess which one the ice slid out of. The
steel pan had ice remnants sticking to it after most was
chipped out. Yeah, pretty unscientific but.... Think
about your plastic ice server bucket when guest come over,
the ice sticks to everything even fingers. At least
modern technology has provided us with some options.
