I had my 90 440 out today and it started bogging down. It was almost like it was running really rich but I couldn't get it to rev up. The motor is stock with dual carbs and a kerker exhaust. There's also a new noise coming from the engine. It's hard to explain the sound but it almost sounds like something small is rattling around in there. I checked compression when I got home and both cylinders were 120. I checked them a few days ago and they were both 150. Any ideas on where to start?
