I’ve seen faulty crankcase recirculation check valves on these motors many times…. it will cause a very rough idle, along with more smoking at idle. But it wont affect the running quality of the engine at higher RPM’s. I think there are at least six of them located behind the carbs on the intake. They are a one way check valve that can stick open. BRP is proud of them too.
