That is a correct statement. That is why I say always use super, and stabilizer. Because unless you pull the carb. And douche it out. You will eventually have issues if you just let it run out of gas using regular .
It's absolutely fine to run the blower out of gas. If it was super. Especially with Sta-Bil in it. Yes correct. I advise against it if it was regular gas.
If it's empty for awhile like you said. There's nothing to drain from carb most likely. But yes. Drain the card of that bad regular gas, if there6any in there. Regular gas is shit. Never use it in any small engine.
Bad to leave the snowblower with no gas. Fill it up with super unleaded, and an ounce or 2 of Sta-Bil. Start it every once and a while for a couple minutes. SUPER UNLEADED. You will thank me if you do that .
