It happened probably a year ago but I have no idea how old the OPS I have really is because I picked it up new open box for $100. I hope they did change that but from the looks of the carb body in that pic it really looks identical to the carb I had problem with. After the first time I was super anal about making sure the linkages were perfectly adjusted so it would not put a load on the idle screw by pulling it too far but it still happened. Also the engine ran a lot more consistant better with the Hyper .21 carb on it. I love the engine and if I had the chance to get another one on ebay for $100 I'd be all over it!

Here are some pics of the stock OPS that engine is based on for comparison.
