I got a 25hp kohler gdlt and when she runs she runs strong, but the other day while I was running I noticed the choke slides out when I give it gas. It ran fine all last weekend until sunday. I noticed that if the choke is all the way in it doesnt run smooth at wot and starts to cut out. If the choke is out a little it runs good, but eventually cuts out at wot. I just had the carb cleaned and run ethanol free gas along with a little seafoam in it. What causes the choke to slide out when I give it gas and eventually cut out? Thanks
