I rebuild Zenith Carburetors using flow tested jets. I have found that after 2 years of ethanol use and storage by some of my fellow club members that the jets have reduced capacities of up to 5%. This can cause poor idle and lower high speeds and sticking float valves. I have often wondered, across the United States how many millions of dollars are wasted on premature repair of fuel handling parts due to ethanol. Ed
