All of those (except maybe the Camaro and Polaris) are low RPM low power low heat engines. These seem to be less prone to the problem - but it’s a huge problem for motorcycles and boats for sure, and it’s not unknown even with lawn equipment.
Just because you’re not having problems doesn’t mean that problems aren’t widespread. Also, when was the last time you checked inside the Camaro’s fuel bowls?
I’ll let you know when stuff starts breaking down.
Or maybe I’ll die first.
All my stuff and me is old and getting older.
Well except my other street cars.
