It shouldn't except for the Ethanol(Corn) lobbyists keep pushing for higher percent of alcohol in the gas mix. Used to be 10% was the tops(and things were rated for that) but there have been recent pushes to increase to 15%. IIRC - the upper limit was increased but the refiners for the most part haven't mixed 15% yet over warranty/liability concerns. Plus the fact we are flush with oil now.

Also likely that high density population centers have special gas in an attempt to limit ozone. Might be those mixes react poorly to open bowl vents on carbs as most cars are now fuel injected.
