I too have had carb ice in the clouds, cold OAT. Noticed low power (full to
maintain alt.) Carb heat solved it. Never had a problem on final but then
I didn't have that many IA's in the cold/clouds.

I have had it quit on short final (in a PA-28-181). Almost exactly
the situation you described -- ILS on a cool day with very small
temp/dp spread, low vis, low scattered layer. Over the airport
boundary, I pulled the throttle back to idle to land and things got
quiet. I was on the ground almost before I had a chance to realize
what went wrong. Hung out for a while on the runway while the ice
melted then started up and taxied off. Had a mechanic look at it, he
found no problems, so we assumed carb ice.

From that day on, I used carb heat in Pipers on instrument approaches.

I've also gotten carb ice in an Archer at cruise power in clouds.
