We were gifted a 2015 primavera 50 4v that had 62 original miles on it and had not run in 3 years. When we got it home it would not start. Now we have gone over the entire carb and replaced the plug and gas and it will now start and run. The issue we are having is that when you start it, it idles VERY high. I can adjust the idle screw all the way out and it doesn't change. I have not played with the fuel mix screw, but I am wondering if that is my next item to check. Any thoughts?
Thanks
