Default Running your carb dry?gas engine

Out of habit, I've always emptied the tank and ran the engine dry on my glow engines then squirting a little after run oil in the crankcase vent tube. Now that I've got 2 gas engines, I've also read that the methanol in today's gas deteriorates the carb rubber parts in the Walbros. Members of my club that have run gas engines for 10 years never empty their tanks or run the gas out of them unless it's the last run before storing them for the winter. I noticed they do have to rebuild the carbs every onece in a while.

Is it advisable to dry run the engines and add after run oil in gas engines after each flying session or is this a waste of time?
