How sad that after all these years carb heat is still a problem
Quite.
When I was looking for a plane to buy in 2002, I decided to simply not even look at anything that had a carb.
Why the industry puts up with this, I don't know, when perfectly good fuel injected engines exist and have done for decades. I suppose it is a marketing decision to offer FI only on the bigger ones, because a fuel servo (e.g. the Bendix RSA5AD1) costs a few hundred $ more than a carb.
