Yep, 100% possible I had carb heat on seemed to clear it up a bit then I
decided to descend and it iced up all the way untill engine out with carb
heat on.

But you were descending. Along with using carb heat, one needs to remember
to push the power up every now and then so that the engine is actually
providing enough heat to melt the ice.

Your experience isn't an argument in favor of partial carb heat.
