[QUOTE="Pappy, post: 490786, member: 3278"] [size=5]Okay, Right off the bat.....if the engine can be idled down and is smooth at idle it is not lean and there should be no need to rebuild the carburetor(s). Typically your symptoms are consistent with an engine that is over propped or your carburetor to ignition pick up point is too early. What RPM are you running at WOT with your typical load onboard? If you are more than around 3-400RPMs below what you should be running at you may need to adjust pitch (prop shop) or change props. On the sync and link side adjust your carb pick up point to come in later. This will allow a bit more ignition timing to occur before the carbs begin to open. I would try this before doing anything else. [/size] [/QUOTE]
