Howdy, basstrk. Sounds like one of your carbs has a clogged up low speed circuit or one cylinder has poor spark at low speed. Disconnect one plug at a time and see how it affects the low speed running. One cylinder probably makes little or no power at idle. Then go after fuel and spark troubles for that one.<br />Good Luck.<br />JB
