I have a 2002 XR6 150 #0t589517. It idles well, but when I go to get on plane it sounds like it is missing pretty bad (maybe around 3000rpms). Then once I'm on plane it smooths out and hits top end just like it should. My guesses would be a coil acting up or possibly a carb jet plugged. Has anyone else had this same problem? Is there a way to test a coil that only acts up under load? It started a month ago when I had it out. I changed the plugs (which didn't look bad) and it is still acting up. Also it got a new fuel line and primer bulb a year ago when I bought it.
