Snowblower won’t start : first quick thing to try

Carburetor cleaning on Ariens :
These last years, I heard people before had no issues with starting snowblowers after summer storage. Imagine how many people have these issues and have to spend money to bring their snowblowers in for a fix – perhaps every year. What happened? Is the the gas got worse because of the Ethanol content, or the new carburetors are made different and more sensitive to Ethanol? With the risk of starting a debate, next year no more storage with gas in the tank – I will make sure it’s 100% empty. By the way, some gas stations say their 91 gas is without Ethanol (I think Shell says this), but my nearby Shell still has Ethanol in the 91 – not rare for a gas tank to ‘leak’ some 87 into the 91 tanks, has already happened in the past (google up).
